“Lollipop” was Millie Small.
“Lollipop” was the Chordettes, 1954.
Millie Small did “My Boy Lollipop”.
Just Googled “Lollipop” and all the songs with that title came up.
I guess my little gray cells, they still work sometimes. “Inspector Poirot”.
Chordettes was correct. Millie Small covered My Boy Lollipop.
