The Hamsters:

Three powerful rodents from Essex who proudly proclaim that they are "the UK's most popular touring blues-rock band, also the leading interpreters of the music of Jimi Hendrix and now ZZ Top!"
And I don't dare to protest!

The amazing lineup:
Snail's-Pace Slim: guitar, vocals
Ms. Zsa Zsa Poltergeist: bass, sings a bit
Reverend Otis Elevator: drums, sings a bit

an extremely professional site: lots of sound clips (dig that "Crossroads"!), nifty album covers, photographs etc. A must!
