Pete used to tell his audiences of how the two hit versions actually harmonized, as a good moral to such things.

What he would say about that version, I don't know, but I hope "poor Pete" and Lee Hays got their royalty check, because some retrebutions were owed. Now I want to run out and rent Debbie in "The Singing Nun" to see what she did with THAT!

Somehow that clip managed to make love between your brothers and sisters sound as distasteful as incest.
