No apologies necessary Sonic....just the term "pal" has always been a sore spot with me. Please accept my apologies for raggin' on ya. And as a matter of fact, yes I have done a gig in a hanger. The best thing about the gig was that we were set up on the wings of a Mars water bomber. They had rubber matting laid down so we weren't slip sliding all over the place. It was a little hairy to say the least, and as you can well imagine...the sound....literally "In Your Face". I may have some pics somewhere, if I can find them. I'll have to scan them if I do find them as it was back before the days of digital imagery.
...peace..
