In reply to Blue Straggler:
Growing up in London in the 60's and going to "Implosion" at the Roundhouse, Chalk Farm - I was really spoilt I suppose.
Some unknown "folkie" called David Bowie, Parliament/Funkadelic, Stones, Floyd, Hawkwind and many many others - cannot remember who were the supports as I was ver...ver... stoned at the time
Famous support acts I can remember would be Siouxie and Banshees (1`st gig) and The Clash supporting The Sex Pistols at The 100 Club.(The Clash blew the others offstage)
Somew unknown band called Roxy Music supporting Bowie(Ziggy Stardust) at The Rainbow.
Too many more to mention, but then I suppose music and mountains have been the two big passions in my life.
