Linen,
I had this tape, knew Barb and several of the artists on the tape. I saw her perform live many times, back in the late 80s when I was in college in Syracuse.
I stupidly loaned the tape to a woman who refuses to return it. If I ever get it back, or learn of how to find another version of it, I'll let you know. BUt so far I too have been luckless!
