The song is written by Lou Christie and Twyla Herbert, and recorded by Christie on the MGM label. The song was arranged, conducted, and produced by Charles Calello and was recorded on September 3, 1965. It was a giant hit in 1966, making it first to #1 in Canada in January 1966 on the RPM Top Singles chart, then to #1 in the U.S. on the Billboard Hot 100 chart in February. It was covered years later by the New York underground artist Klaus Nomi, appearing on his 1981 debut album Klaus Nomi, and was the A-side of a 1982 single accompanied by a video. Because of Christie’s falsetto wail during the chorus, the song is often miscredited to Frankie Valli and The Four Seasons.
