Can anyone provide any information on a Welsh psych/prog band called HUMAN LEG who were in existence from approx 1969-1971

only this from: http://link2wales.co.uk/

Human Leg – Swansea band (1969-71), feat; Spiv Morris (voc), Tweke Lewis (gtr), Phil Gov (bass,voc), Ray Thomas (drms). Wrote material which reflected the lives and social structure of the day (1969). They toured the UK and played the original Liverpool Cavern Club, also had a big following in Swansea and South Wales, and were big friends of the Man band.
