A. “I Lost My Little Girl” is the first song Paul McCartney ever wrote. He was 14 years old when he penned it, and the year was 1956. He wrote it using a Framus Zenith model 17 acoustic guitar that he kept throughout his life.
The song wasn’t officially released until 1991, after McCartney performed it for MTV Unplugged. There’s also a rehearsal version of it sung by John Lennon during the Beatles Get Back Sessions.
