I come from the past.
Back in 1973 I purchased the Heaven & Earth LP after my third pay day. 50p -TEN SHILLINGS! I still have the LP in perfect condition but no record player.
For 30 years I searched the internet, music mags and anywhere else I could to find more info on them. Nothing. People thought I was making this all up then, about ten years ago I got an email from a fella who had the LP and put it onto disc -he sent me a copy.
40+ years on everyone is NOW discovering the group! Which means that I've been enjoying the songs for longer than 99.8% of those now jumping into the groove!
