Smooth, quick, but unfortunately, stolen. When they were in Hamburg in 1962, the Beatles did a live performance of "Talkin' About You" by Chuck Berry. The bass riff was taken by Paul for his 1963 song "I Saw Her Standing There".
Also, the song was about McCartney's girlfriend, Cecilia Mortimer, who was 17 at the time. Paul was 21.
Backing track comes from Michael Sokil's cover of "I Saw Her Standing There" - @ephemera2010
I used a Höfner for the first time.
Coincidental, due to the fact I turned 17 the day I uploaded this.
