Fishboat,
Is this the site you were referring to in Spain? Flamenco-World? Since the original recording was from Spain, you might stand a better chance of finding one there.
Did see an original album on ebay (Vol 1 I think). Guy's from Spain and wants $180.00 for it. Ends in 6 days. Ouch!
Keep your eye on Gemm. Titan Music has one listed. Titan Music Not highly rated but you may get lucky.
Will keep checking.
