First of all welcome Spocksbrain.....

Nice to have you.
Second (and maybe I'm missing something here),you say your looking for shows from
the 80s but then you said "What I'm looking for "our "concerts from around 84 or 85 .
Are you looking for concerts you had but lost or just in general?
Let me know either way. I can;t help in locating any but I'm just a touch confused.
