The 1982 Mobile date is actually one of the newest added, thanks to a poster on ebay. As for the show your looking for, maybe it was late '79? I know Jimmy did a Hurricane Benefit in Mobile in late '79, just don't know the actual date. My only suggestion on how to find the show is to check the Mobile Press-Register archives for that time, I'm sure they did a review.
Hey Mr. Moustache look what weâ€™ve done
Lived longer than they thought we could do
Through all of the games and all of our fame
We learned to stay cool from you
