In 1969, Terry Britten (ex-the Hurricanes, The Twilights, when living in Adelaide) joined the trio on guitar, in London, to form Quartet, which released two singles, "Now" (December 1969) and "Joseph" (May 1970) on the Decca label and recorded a 13-track unreleased album. The group disbanded later that year. In 1973 Britten, Spencer, Tarney and Australian-born John Farrar (ex-the Strangers) on lead guitar, were the backing band for Cliff Richard on his Eurovision Song Contest 1973 entry, "Power to All Our Friends".
