Paul McCartney and John Lennon just couldn't keep their songs to themselves. In addition to the Beatles' unmatched catalogue, the talented songwriting duo penned dozens of diddies for other artists including Fame, co-written by Lennon and performed by David Bowie, the 1964 hit A World Without Love, written by McCartney and recorded by the English duo Peter and Gordon, and the chart-topping single Come and Get It, also written by McCartney and performed by Badfinger. Even the Rolling Stones borrowed from the Beatles. The band released their version of the McCartney/Lennon song I Wanna Be Your Man three weeks before Lennon and McCartney did.
