In 1975, John Lennon was reconnecting with his roots via his Rock 'n' Roll album, which saw him covering some of his favorite songs from the genre's early days. "You might call it 'Oldies but goldies,' I was calling it 'Oldies but moldies,'" he joked.

"Some of them were the first songs that I learned that were rock and roll," he said. One of those songs was Gene Vincent's "Be-Bop-A-Lula," and he notes that the first time that he ever performed it in public was the day that he met his future Beatles-mate, Paul McCartney.
