(born June 18, 1942, Liverpool, Eng.) British vocalist, songwriter, composer, bass player, poet, and painter whose work with the Beatles in the 1960s helped lift popular music from its origins in the entertainment business and transform it into a creative, highly commercial art form. He is also one of the most popular solo performers of all time in terms of both sales of his recordings and attendance at his concerts.

McCartney's father, James, worked in the Liverpool Cotton Exchange, and his mother, Mary, was a midwife, out at all hours on her bicycle to deliver babies. Her death from breast cancer in October 1956, when McCartney was age 14, had a profound effect on his life and was the inspiration for his ballad “Let It Be” (1970). His younger brother, Michael, later changed his name to Mike McGear and had a number of hits in the satirical rock group Scaffold. Like fellow Beatles George Harrison and Ringo Starr (Richard Starkey), McCartney grew up in a traditional north of England working-class society, with an extended family frequently visiting the house at 20 Forthlin Road in the Allerton area of Liverpool (the house is now owned by the National Trust). His father had been the leader of Jim Mac's Jazz Band, and in the evenings the family often gathered around the piano, an experience McCartney drew upon for such sing-along songs as “When I'm 64” (1967).

On July 6, 1957, he met John Lennon at Woolton Village Fete and joined his skiffle group, the Quarrymen, which, after several name changes, became the Beatles. When Lennon's mother was killed by a speeding police car in 1958, McCartney, with his own mother's death still fresh in his memory, was able to empathize with the distraught 17-year-old, creating a bond that became the basis of their close friendship. McCartney and Lennon quickly established themselves as songwriters for the group, and, by the time the Beatles signed with EMI-Parlophone in 1962, they were writing most of their own material. By their third album the group stopped recording covers. Lennon and McCartney's songwriting partnership was very important to them, both financially and creatively; even in 1969, when they were estranged over business matters and supposedly not on speaking terms, Lennon brought McCartney his song “The Ballad of John and Yoko” and they worked together on the “middle eight” (the stand-alone section that often comes midway in a song). Their music transcended personal differences.
