In the beginning, this new band consisted of Ole "Sir Henry" Bredahl (vocals, bass) and Carsten Elgstrøm (guitar), together with Leif Davidsen (drums).
Shortly thereafter, the band was expanded with Poul Petersen (guitar) and Leif Davidsen was replaced with Jens Bøgvad, former the Flintones.
In January 1965, Sir Henry and his Butlers expanded the band (Ole Bredahl, Torben Sardorf, Arne Schrøder) with Tommy Seebach (organ and, vocals), who at the time was only 15 years old.
The same year the band changed record label to EMI and achieved a number of hits, among others: Times Are Getting Hard, Beautiful Brown Eyes and "Marianne", which were all released in 1966.
The distinctly odd B-side song, "Pretty Style", featured sitar and psychedelic multi-tracked guitar and vocals.
Ole Bredahl and Tommy Seebach decided in 1975 to reorganise the group together with Torben Johansen (guitar) and John Roger (drums); the latter was a former member of Teenmakers.
At the Dansk Melodi Grand Prix in 1983, they participated as backing group for Kirsten Siggaard with the song "Og livet går".
