About The Chiffons
The Chiffons were an American girl group originating from the Bronx, a borough of New York City, in 1960. Shortly after the first round of hits, the Chiffons had business problems but still continued to tour the US throughout 1964 (including Murray the K Shows and as part of a package tour headlined by Gene Pitney). To promote the record, Sylvia and Barbara flew to the West Coast to premiere the disc on a July 1965 Shindig episode, with two substitute members as Judy and Pat were on maternity leave. The Chiffons did their first overseas tour of England and Germany in June 1967; on one of their London club dates (the Chiffons were one of the opening acts for Jimi Hendrix), members of the Beatles and Stones were in the audience.
