For no particular reason, I invite you to watch Donovan on The Smothers Brothers Comedy Hour.
This was from the same show where George Harrison made a surprise cameo, so there is plenty of hippie "peace and love" in the air. (Dig the crazy audience that looks like senior class assembly at West Hollywood High).
Donovan was quite good - sort of a cross between Bob Dylan and Paul McCartney; well worth iTuning.
