Patience and Prudence had more success with the song when they recorded it in 1956 reaching #11 on the charts. This is considered the benchmark version, by which all others are judged, due to the intimate harmony of the two young singers. This version brightened the melody somewhat, and later artists followed the brighter version, as did Brewer when she recorded an album version in 1964 in a semi-Caribbean style.
Dey's version was done in a style emulating the Wall of Sound, which was popular with girl groups at the time.
Davis' version reached the Top 10 on Country charts, and is considered by oldies enthusiasts to be "the" cover version. Where the Patience and Prudence version has an orchestral backing, the Davis version has a pop band backing of electronic organ, bass and drums, with violin and backup singers.
Penny Marshall and Cindy Williams, who recorded a version on their 1976 novelty LP, Laverne & Shirley Sing.
Viola Wills (1979), doing a version in "disco" or "dance" style, with a slower tempo and heavy electronic instrumental backing. This is the style done by most later artists. The Viola Wills version of the song peaked at number fifty-two on the disco chart  and number 8 on the UK charts.
