Cliff Bennett and the Rebel Rousers was one of the many British soul bands playing the clubs in the 60's. Along with Jimmy James and the Vagabonds, Geno Washington, Zoot Money and Herbie Goins etc. These were high energy Ike Turner type bands (without Tina) playing James Brown, Stax, Atlantic and some New Orleans music. It was always a great night when you went to see one of these bands.
Cliff was different in that he had at least one hit with a Beatles song, Got To Get You Into My Life, I believe. I think I've got the 45 somewhere.
Cliffs organist was Roy Young who fronted his own band in the early 70's.
