Jim and all,
I agree with Gino. Go out and buy Once Again and Other Short Stories, both from the early 70s. Then go and buy Revival when John and Woolly reformed BJH in 1998. This is a terrific live album and the 'tron is full on. Avoid anything once Woolly had left the band as the heart and soul left at the same time. Pay no heed to David's silly ramblings.
Best,
Martin
