I bought this copy in November 1966, at that tiny underground record shop in Greenwich village, in the same batch of 45's as 'Don't Let Me Sleep Too Long'- Myddle Class. They both had that same exciting, newly-emerging raw energy of the times, and this record became a local hit in several markets across the US in mid-1966.
There's a good write-up on the group at Wikipedia, and the surviving members have reunited and have a home page at \"www.richardandtheyounglions.com/\". See my other posting for the B-side song, \"Once Upon Your Smile\".
