I think this one might be worthwhile sharing (1982-04-16 Zurich) if it is not considered too rare and has VG+ quality or better.
I usually have excellent luck on the hub, but his is one concert that I cannot find with EX- quality on the hub (I know of at least 4 traders that have rated it as EX-). I made at least 3 attempts at several different shares on the hub, but they all had VG- quality ... or worse.
I can live without it, but it would be nice to have in decent quality.
