The band was established in Dublin in 1962 by impresario Tom Doherty. He recruited an existing group, the Downbeats Quartet, comprising Joe Tyrell (piano), Tony Bogan (drums), Clem Quinn (guitar), and Martin Phelan (saxophone), and augmented them with singer Dickie Rock (at the time, a member of another group, the Melochords), trumpeter Tommy O’Rourke, trombonist and vocalist Murty Quinn, and bass player Denis Murray.
In 1967, four members of the band—Murty Quinn, Tommy O’Rourke, Denis Murray and Martin Phelan—split away to form their own group, The Sands. They were replaced by songwriter and singer Fran O’Toole, Paul Ashford, Pat McCarthy, Des Lee (born Des McAlea) and Brian McCoy.
Line-up changes continued, and by 1975 the last remaining member of the original line-up, Clem Quinn, had left. The group then comprised Des Lee, Brian McCoy, Tony Geraghty, Fran O’Toole, Steve Travers and Ray Millar
