I strongly advise that you get on to Kats-Karavan. Some amazing stuff on there.
There's a Perfumed Garden from 1967 with Peel going 100% hippy: playing Zappa; talking about the night he'd just had at UFO; recalling trees in Hyde Park whispering 'dark green words of love.'
Not the best of quality but fuck it; It's still the best thing i've found on the net since god knows when.
