Two Grapevine albums were among a clutch of the rarest folk-gospel-prog-psych rarities auctioned on ebay over the weekend.
The albums I tracked were:
Water into Wine Band - Harvesttime - £460 - 14 bids (and apparently sold by Oxfam)
Whitsuntide Easter - Next Time You Play a Wrong Note GRV109 - £142 - 22 bids
Reynard - Fresh From the Earth GRV 102 - £22.77 - 5 bids
Linda Rich - Apple Tree - £14.82 - 2 bids
All that were missing were Caedmon, Candle Factory and Voiz (GRV 110).
Strictly speaking Whitsuntide Easter and Voiz are rock, not folk - although Whitsuntide is quite folk-rocky.
