The guitar that Tandy bangs on while singing to Lewis is supposed to be John Lennon's 1962 Gibson J-160E as evidenced by the distinctive triangular wear pattern near the sound hole. The guitar went missing in December of 1963 and did not resurface again until 2014 when a man saw photos of Lennon playing it and realized it had the same distinctive wear marks as his guitar. It was sold at auction for $2.4 million in 2015.
