First recorded and released by Louise Cordet (February 1964).
Hit version by Gerry & The Pacemakers (US #4/CAN #5/UK #6/AUS #26/NZ #6 April 1964).
From the wiki: “The song, written by Gerry Marsden, Freddie Marsden, Les Chadwick and Les Maguire, the members of British beat group Gerry & the Pacemakers, was given first to Louise Cordet, a singer who had previously toured with the group as well as with The Beatles. Her version was released on Decca Records in February 1964 with no apparent chart impact.
“Gerry & The Pacemakers then decided to produce their own version. It was released on EMI Records in the U.K. in April 1964 as the group’s fifth single in Britain, where it reached #6 in the UK Singles chart.
“In the U.S., ‘Don’t Let the Sun Catch You Crying’ was the group’s breakthrough single, peaking at #4 on the Billboard Hot 100. The record, like the group’s earlier releases, was produced by George Martin.”
