The Turtles was an American rock band led by vocalists Howard Kaylan and Mark Volman, later known as Flo & Eddie. The band had several Top 40 hits beginning with their cover version of Bob Dylan's "It Ain't Me Babe" in 1965. They scored their biggest and best-known hit in 1967 with the song "Happy Together".
Happy Together appeared on their third studio album Happy Together (1967). The song was written by Garry Bonner and Alan Gordon, arranged by Chip Douglas, and produced by Joe Wissert.
Released as a single in February 1967, the song knocked the Beatles' "Penny Lane" out of the number one slot on the US Billboard Hot 100 and remained atop the chart for three weeks. It was the group's only chart-topper in the United States. "Happy Together" also reached number 12 on the UK Singles Chart in April 1967 and number 2 on the Canadian Top Singles chart in Canada.
The band broke up in 1970. Kaylan and Volman later found long-lasting success as session musicians, billed as the comedic vocal duo Flo & Eddie. In 2010, a reconstituted version of the band, ‘the Turtles Featuring Flo & Eddie’, began performing live shows again.
