McCartney and Starr watch Jimi Hendrix in London

On this evening Paul McCartney saw trumpet player David Mason performing Bach's Brandenburg Concerto Number 2 in F Major with the English Chamber Orchestra from Guildford Cathedral, on the the BBC 2 television series Masterworks. Impressed with what he heard, McCartney decided to use him for the final overdub on Penny Lane.

Mason was telephoned the following day by George Martin, and booked for a studio session on January 17, 1967. There, he added the famous piccolo trumpet solo.

In the evening McCartney and Ringo Starr saw Jimi Hendrix perform for the first time, at one of Hendrix's regular shows at the Bag O'Nails club in London.
