'Dogs' by The Who. Released as a single in 1968.
Trying - by their own admission - to sound like The Small Faces, and failing miserably. A stopgap song in a dreadful year for the band. Thankfully, their next offering was a little more serious and better-received.
A rock opera called 'Tommy'.
Carrying on in the Beatles vein, Frog Song by Macca?
This. I'd love to know what he was on though.
