4. The Intro to 'I Feel Fine' Was Borrowed from Bobby Parker's 'Watch Your Step'
John Lennon was a fan of the Louisiana R&B guitarist Bobby Parker, whose hit song 'Watch Your Step' the Beatles played on stage in 1961 and 1962. The riff inspired "I Feel Fine." "Led Zeppelin used the riff even more obviously, on 'Moby Dick,'" says Freiman.
