a note on the known circulating 28 June 1981 sources ... - there are 4 LB entries listed at lossless Bob for this show - LB-0329, LB-7027 and LB-8278 are derived from the same 'net taper B' recording - LB-8278 is the best quality version of these and has documented lineage from the master recording. It is a great sounding tape that I have been able to noticeable improve - while i suspect the master tape did include the opening set due to the placement of the first tape flip, no opening set from this recording has circulated - LB-8250 is a different recording of much poorer quality - but LB-8250 does include the opening set, 3 of the 4 tape flip gaps in LB-8278 and the missing parts of tracks 16 and 29 that are cut in LB-8278.
