This was written by Phil Spector, Ellie Greenwich and Jeff Barry and produced by Spector. The Crystals, like many of the US girl groups, had a shifting rota of personnel, and I am not sure if this video features any of the singers on the track. It reached No 6 in the States in 1963 and No 2 in Britain.
The Beach Boys reworded the song and retitled it Then I Kissed Her. It was released on their 1965 album Summer Days (And Summer Nights!!) then as a single in the UK in 1967, when it got to No 4.
