For the next few years, the group was in a seemingly constant state of flux. Adding Dakar to the permanent line-up, the group recorded "The Boiler" with Dakar on vocals, Dammers on keyboards, Bradbury on drums, John Shipley (from the Swinging Cats) on guitar, Cuthell on brass and Nicky Summers on bass. The single was credited to "Rhoda with the Special AKA". The track describes an incident of date rape, and its frank and harrowing depiction of the matter meant that airplay was severely limited. Nevertheless, it managed to reach No. 35 on the UK charts, and American writer Dave Marsh later identified "The Boiler" as one of the 1,001 best "rock and soul" singles of all time in his book "The Heart of Rock & Soul".
