Rematch is a the first US-released Sammy Hagar compilation album. After Sammy left Capitol Records for Geffen in 1981, and after Rick Springfield had a hit with the Hagar-penned "I've Done Everything for You", this collection was released to capitalize on that momentum.

The album was originally released as a 10-track LP, but in 1987, Capitol re-released the collection on CD as "Rematch And More", adding five more tracks from the Capitol albums.

The cover depicts a mock-up of a supposed boxing match poster advertisement. This represents Sammy's own early career aspirations to follow in his father's footsteps as professional prize fighter. The "main event" in this ad is between Sammy and a fighter named "Roy Scarlet"; a euphemism using Sammy's actual middle name, Roy, and "Scarlet" which would be the equivalent of "Red" for Sammy's "Red Rocker" moniker.

A second billing is also depicted on the poster, John "Little Red" Galt vs. Bill Church. While Bill Church was clearly the long-time bassist in Sammy's band, it is unclear whether or not John Galt refers to the Atlas Shrugged character.

Andre Michael Berto (born September 7, 1983) is a Haitian-American professional boxer. On June 21, 2008, Berto became the WBC welterweight champion by defeating Miguel Rodriguez by seventh round technical knockout. He lost his WBC welterweight title on April 16, 2011 to Victor Ortiz via unanimous decision. Berto bounced back in his very next fight on 4th September 2011, to defeat Dejan Zaveck and became the IBF welterweight champion, until he vacated it.

Raised one of seven children in Winter Haven, Florida, Berto was introduced to boxing by his father after getting beat multiple times by him. Dieuseul, who competed professionally in mixed martial arts and taught the sport at a school in Winter Haven. For Berto, the sport of boxing became a solace to stay out of trouble. His brother, James Edson Berto, is a professional mixed martial artist. Berto is often called "Mike", his middle name.

As an amateur, Berto won a bronze medal in the 2003 World Amateur Championships. He was also a two-time National Golden Gloves champion, a two-time National PAL champion, a three-time U.S. amateur championship medalist, and also won 22 state titles in Florida.

Joe Cortez (born 1945 in New York, New York) is a Puerto Rican boxing referee who has officiated in many important world title bouts.

Cortez moved to Puerto Rico during his childhood. Living there, he became fluent in Spanish. Cortez had a good amateur boxing career, winning various Golden Gloves tournaments from 1960 to 1962. In 1963, at the minimum age of eighteen, he jumped into the professional boxing ranks. Cortez had a record of eighteen wins and one defeat as a professional boxer. Unable to secure a world title shot, however, he retired from boxing after only nineteen professional fights.

Beginning in the early 1970s, Cortez started working as a referee. During the 1980s, he took on the responsibility to referee some important, but not big, fights. During this time he was the third man in the ring in several of Mike Tyson's pro fights.

As eminent referees Richard Steele and Mills Lane retired at the dawn of the 21st century, Cortez became one of Nevada and New York's preferred boxing referees for world title fights. He has refereed over 170 world title bouts, among which figure the first Oscar De La Hoya-Julio César Chávez meeting, Evander Holyfield and Riddick Bowe's first title fight and the match that saw 45-year-old George Foreman become the oldest World Heavyweight Champion in history. Asked by Telemundo personnel to give a prediction about the first de la Hoya-Chávez meeting prior to the fight taking place, he simply answered "I can't make any predictions", as referees are not allowed to do that before a fight (doing so might indicate favoritism towards one of the combatants).

Nathan Cleverly (born 17 February 1987) is a Welsh professional boxer and current WBO light heavyweight world champion. He is also the former European, British and Commonwealth light heavyweight champion. He graduated with a BSc in Mathematics from Cardiff University in 2010.

Cleverly made his professional debut in July 2005 with a four round victory over journeyman Ernie Smith at the Meadowbank Sports Center in Edinburgh and within a year had compiled a winning ledger of 6–0. His first fight of substance however was in October 2006 when he met Liverpool's Tony Quigley at the MEN Arena in Manchester. The fight which was on the undercard to the match up between Joe Calzaghe and Sakio Bika ended in a 5th round stoppage for Cleverly and handed Quigley his first pro defeat.

The next big test for the young prospect took place at the Millennium Stadium in Cardiff just over a year later in September 2007 when Cleverly met tough Ugandan Joey Vegas. Cleverly at that time boasted a record of 10–0 and Vegas 10–1. The fight ended with a gruelling points win over 8 rounds for the Welshman in what was his toughest fight to date. Speaking about the result to the BBC and referring to the sparring he received in the Enzo Calzaghe gym, Cleverly said "I'm still young and won't be hitting my peak for about eight years, but think how good the wars I'm having in the gym now are doing me for the future ... I want to keep on progressing, to go for the British title, then maybe a world crown in a couple of years."

Tony Bellew is a British professional boxer and a former three time ABA Heavyweight Champion. He is promoted by Frank Warren, trains out of Arnie's gym in Manchester and is the reigning Commonwealth light heavyweight champion.

Fighting out of Liverpool's Rotunda ABC, Bellew claimed the both the 2002 and 2003 novice ABA title's by knocking out every man he faced with the exception of Rob Hough who went the whole 3 rounds from Paramount ABC (Stockport) in the under 10 bouts championships. Then, when he was eligible for the Senior championships, he stepped up to the 91 kg heavyweight class and added even more titles to his collection. In 2006 he lost to Danny Price.

The 27-year-old, a three-time ABA heavyweight champion, is hoping to emulate the feats of his home city's most famous fighter, John Conteh. Like Bellew, Conteh was an ABA champ, before winning British, Commonwealth, European and WBC titles at 175 pounds. And Conteh has even backed Bellew to match his achievements, revealing that he will be keeping a close eye on his career. "John is a big hero of mine, one of the best fighters to have come out of the UK, if not the best, and I'd love to go on and achieve what he did," said Bellew. "To be talked about in the same breath as him is pretty amazing. I've met him a few times and he's a great guy, although I'm not sure he knew who I was! Once I start winning titles, hopefully that will all change." Bellew, who fought out of the world famous Rotunda ABC as an amateur, did not start boxing until he was 17.
