We missed this important anniversary, but it bears relating. On July 6, 1957, a 16-year-old John Lennon and his skiffle band The Quarry Men were playing for a church function in Woolton just outside Liverpool. A mutual friend introduced Lennon to Paul McCartney, then 15 and a pretty good guitar player and singer. A few days later McCartney was invited to join the band. Then they wrote and recorded some stuff.
