Back around 1973, a friend had this song on a reel-to-reel tape with The Moody Blues' "Days of Future Passed" album. We were at his house one day playing the tape in the living room and his dad was there reading a newspaper. His dad reminded us of Tom Bosley from Happy Days. We were 19 at the time.
When this song came on, he lowered the paper, and asked (incredulously), "What the hell is this?!"
