Oh, I love this! Starts off like the Mamas and Papas and becomes an almost baroque-pop, flower-power anthem from 1967....Four years too late, but what the heck!
Brilliant song. For me it's the most memorable song from the film. I remember watching it when I was an 8 year old kid back in 1978. Never forgotten it. Im 53 now and love reminiscing it.
