I need a little help. I remember a tape I've owned in the eighties and lost when moving after my divorcee, which included the so-called "Fingerprint File" live demos. If I remember exactly I've got them from a french guy I've been trading a lot with these days and it have been two complete (uncut/unedited) versions of "Fingerprint File" live 1975 in amazing soundboard quality! Anybody out there who has got 'em and could help me out???
