Hey,..... I was there. I heard them sing. I know the words by heart and posted them.
Back when I was in sixth grade outside of Philly, I heard one radio DJ do that - - slow the record down by just a hair.
That’s my memory of the bit. We had just moved to the US from four years overseas; being back in CONUS was wonderful. Some times I would turn our TV antennae toward New York so we could watch Soupy Sales. My mind was warped from all its exposure.
