Hi, I've been in a 8 track mood recently. I got most of the series in 2 lots from the auction site. It seems that there are about 4-5 in the series that were released on vinyl but not 8 track, for example Bessie Smith, Lester Young, Frank Teschemacher. Can someone verify this please? Then I can stop looking to try and 'complete' the series! Cheers
