"Secret Agent Man"!! What a great tune!
Johnny Rivers had tons of hits, starting with covers of "Memphis" and "Maybelline."
Written by P.F. Sloan. Check out the great Jimmy Webb song, "P. F. Sloan." (Johnny Rivers recorded several Jimmy Webb songs; one of JR's albums, Rewind, was mostly Jimmy Webb songs.) The Association did a great version of "P.F. Sloan."
