One line only, trying to identify the song / ad / source
 

I dont have the lyrics, except the first word is, "Ooohh.."
I keep trying to guess the lyrics but I'm unsure.
So, I have the audio snippet. It's less than 6 seconds.
Date recorded was Feb 20th 1970.
But it might be a TV ad from the end of 1969.
It is not from the actual ad itself.
It might not be an advert.
This was sung between songs by Elvis Presley.
It is NOT an Elvis song.
Just found out I can't attach a small mp3 file.
So, I've uploaded to youtube:
