I never got into John Fred, but I think this Turtles single has to be one of the great pop hits (even though it wasn't written by the Turtles themselves).

But one year later (1968), the group released what is probably the greatest American concept album, "The Turtles Present The Battle of the Bands."

I'll post a Riff review later. Spoiler: the subtexts of this deceptively complex album are nuclear war and artistic integrity.
