Perry grew up with gospel music, and during her first year of high school she pursued a music career as Katy Hudson, releasing her first studio album called Katy Hudson which failed to chart. She recorded a solo album later, which was never released. After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry.

She first gained recognition with the release of her first mainstream album, One of the Boys in 2008, which spawned three Billboard Hot 100 top-ten songs—"I Kissed A Girl", "Hot n Cold" and "Waking Up In Vegas". Perry supported the album with her Hello Katy Tour. In 2010, her third studio album, Teenage Dream (2010), which topped the Billboard 200 chart, and spawned five number one singles—"California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)"—Teenage Dream was the only album (after Michael Jackson's Bad)—to do so, and the first female in history to achieve this milestone. She embarked on the California Dreams Tour, which grossed nearly $60 million worldwide. Perry re-released the album under the name of Teenage Dream: The Complete Confection on March 26, 2012, and the re-release has already spawned the number-one single "Part of Me".

Tortorella has been credited by East Coast Hockey League founders Henry Brabham and Bill Coffey with coming up with the name for the league during a league meeting at a Ramada Inn in Winston-Salem, North Carolina. At the time Tortorella was the head coach of Brabham's Virginia Lancers, but left the Lancers to become the assistant coach of the American Hockey League's New Haven Nighthawks before the ECHL's inaugural season in 1988.

Born in Cathedral City, California, and training out of Indio, California. He is the current WBO Light Welterweight Champion and former two-time WBC Light Welterweight Champion.

Bradley finally got his chance for the title when José Luis Castillo failed to make weight in a title eliminator for the full WBC Light Welterweight belt. He then won the WBC Light Welterweight title by defeating British fighter Junior Witter in England.

On 4 April 2009, Bradley fought Kendall Holt to unify his WBC and Holt's WBO titles. Bradley was dropped in the first round by a huge left hook and was badly hurt but regrouped and outboxed Holt for most of the fight, before being sent to the canvas again in the 12th round. Nonetheless, Bradley got up and finished the fight. He won the fight by unanimous decision and became the new WBO Champion.

John Albert Elway, Jr. (born June 28, 1960) is a former American football quarterback and currently is the executive vice president of football operations for the Denver Broncos of the National Football League (NFL). He played college football at Stanford and his entire professional career with the Denver Broncos. Elway recorded the most victories by a starting quarterback at the time of his retirement. He retired in 1999 and statistically was the second most prolific passer in NFL history. Elway led his teams to six AFC Championship Games and five Super Bowls, winning his last two.

Elway set several career records for passing attempts and completions while at Stanford. He also received All-American honors. Elway was drafted #1 overall in the 1983 NFL Draft by the Baltimore Colts before being traded to the Denver Broncos. In 1987, he embarked on what is considered to be one of the most clutch and iconic performances in sports and in NFL history, helping engineer the Broncos on a 98-yard, game-tying touchdown drive in the AFC Championship Game against the Cleveland Browns. The moment is known in National Football League lore as "The Drive". Following the AFC Championship Game, Elway and the Broncos lost in Super Bowl XXI to the New York Giants. It would be the first of a record five Super Bowl starts at quarterback in Elway's career, a record that he solely held until 2012 when Tom Brady earned his fifth Super Bowl start.
