Harry Nilsson's amazing voice remains one of the aural icons of the 60's and early 70's. He's sung a number of songs that are woven tightly into the cultural tapestry of that era.
I really enjoyed these few minutes with Harry. Years later, he and John Lennon would make headlines for being kicked out of a Smothers Brothers performance, where they were in the audience heckling Tommy and Dick.
