A base on balls (BB) is credited to a batter and against a pitcher in baseball statistics when a batter receives four pitches that the umpire calls balls. It is better known as a walk. The base on balls is defined in Section 2.00 of baseball's Official Rules, and further detail is given in 6.08(a). It is called a "walk" because the batter is then entitled to walk to first base, or more specifically (as defined in the rules of baseball) he is "entitled to first base without liability to be put out." However, the term "base on balls" is used in official context because it is considered a faux pas for a professional player to walk to first base (as opposed to physically running), and also to distinguish from the other manners in which a batter can be awarded first base without liability to be put out (e.g., hit by pitch, catcher's interference).

A batter who draws a base on balls is commonly said to have been "walked" by the pitcher. When the batter is walked, runners advance one base without liability to be put out only if forced to vacate their base to allow the batter to take first base. If a batter draws a walk with the bases loaded, all preceding runners are forced to advance, including the runner on third base who is forced to home plate to score a run, and the batter is credited with an RBI per rule 10.04.

Henry (Hank) Mobley (July 7, 1930 – May 30, 1986) was an American hard bop and soul jazz tenor saxophonist and composer. Mobley was described by Leonard Feather as the "middleweight champion of the tenor saxophone", a metaphor used to describe his tone that was neither as aggressive as John Coltrane nor as mellow as Stan Getz. In addition, as his style was laid-back, subtle and melodic, especially in contrast with players like Sonny Rollins and Coltrane. The critic Stacia Proefrock claimed he is "one of the more underrated musicians of the bop era."

Mobley was born in Eastman, Georgia, but was raised in Elizabeth, New Jersey, near Newark. When he was 16, an illness kept him in the house for several months. His uncle thought of buying a saxophone to help him occupy his time. It was then that Mobley began to play sax. He tried to enter a music school in Newark, but couldn't, since he was not a resident, so he kept studying through books at home. At 19, he started to play with local bands and, months later, worked for the first time with musicians like Dizzy Gillespie and Max Roach. He took part in one of the earliest hard bop sessions, alongside Art Blakey, Horace Silver, Doug Watkins and trumpeter Kenny Dorham. The results of these sessions were released as Horace Silver and the Jazz Messengers. They contrasted with the classical pretensions of cool jazz, with Mobley's rich lyricism being bluesier, alongside the funky approach of Horace Silver. When The Jazz Messengers split in 1956, Mobley continued on with pianist Horace Silver for a short time, although he did work again with Blakey some years later, when the drummer appeared on Mobley's albums in the early 1960s.

Mathis James "Jimmy" Reed (September 6, 1925 – August 29, 1976) was an American blues musician and songwriter, notable for bringing his distinctive style of blues to mainstream audiences. Reed was a major player in the field of electric blues, as opposed to the more acoustic-based sound of many of his contemporaries. His lazy, slack-jawed singing, piercing harmonica and hypnotic guitar patterns were one of the blues' most easily identifiable sounds in the 1950s and 1960s, and had a significant impact on many rock and roll artists who followed, such as Elvis Presley, Billy Gibbons and the Rolling Stones.

Reed was born in Dunleith, Mississippi in 1925, learning the harmonica and guitar from Eddie Taylor, a close friend. After spending several years busking and performing in the area, Reed moved to Chicago, Illinois, in 1943 before being drafted into the US Navy during World War II. In 1945, Reed was discharged and moved back to Mississippi for a brief period, marrying his girlfriend, Mary "Mama" Reed, before moving to Gary, Indiana to work at an Armour & Co. meat packing plant. Mama Reed appears as an uncredited background singer on many of his songs, notably the major hits "Baby What You Want Me to Do", "Big Boss Man" and "Bright Lights, Big City".
