Badfinger were a British rock band formed in Swansea in 1961. Their best-known lineup consisted of Welshmen Pete Ham, Mike Gibbins (drums), and Englishmen Tom Evans (bass), and Joey Molland. Initially known as the Iveys, the band renamed themselves Badfinger, after the working title for the Beatles' 1967 song "With a Little Help from My Friends".

They are recognised for their influence on the 1970s power pop genre and are estimated to have sold 14 million records.
