OK, more 50's: This pop classic was 1st recorded by Della Reese and The Honey Dreamers in '57 (#9 Billboard). The melody comes from "Autumn Concerto", an Italian instrumental by Camillo Bargoni. English lyrics by A. Stillman and P. Siegel. Kay Starr's version under a slightly different name also peaked at #9. The Four Seasons' '69 cover reached #45 and happens to be my all-time fave song of theirs.
Yesterday's answer: "Hi Lili, Hi Lo". Featured in the 1953 Leslie Caron film "Lili". http://www.youtube.com/watch?v=h9_whtCO5e0
