McCartney's solo release "Wings Wild Life" contains a song titled "Tomorrow" which not only parodies "Yesterday" in the title, but also borrows the first four chords, albeit transcribed to the key of D major.
The original recording is the first to feature only one of the Beatles.
Paul McCartney tunes his guitar one whole tone lower than standard for the recording of this song. Thus his playing in G Major is tonally actually F Major. [thanks to Abdo Adeshttp://www.abdopiano.com]
