legendary musician recalled that he initially wanted to play guitar for the band instead of bass. However, his hopes were dashed after an incident at a show early in his career.McCartney explained that he was good at playing the guitar while “at home,” and bandmate John Lennon’s aunt, Mimi Smith, used to tell him that he was “much better than John.”“Mind you, when I first met John, he played banjo chords,” McCartney remembered.
