Summer of 1972...the song is "Too Late To Turn Back Now' by The Cornelius Brothers and Sister Rose.
In the bridge of the song, one "brother" sings the most convoluded lyric in the world...
He sings and my sister and both heard him warble this: "I wouldn't mind da if I nooped do really love me doo".
The advent of PCs and the Interent and posting of lyrics revealed that said brother was actually singing, "I wouldn't mind it, if I knew she really loved me too".
Well maybe, but this one Cornelius brother did it with marbles and mayonaise in his mouth.
Also in the oringal early 60
s son "Last Kiss", listen for the part where the soprano singing in the background goes flat and her voice falls and trails off.
After the lyrics..."that I heard last"..
And they actually left that in the master recording.
Hilarious. .
