Will not hurt to make the 'follow-up' call, which is all that it is. Then you'll know one way or the other. Just waiting for the other shoe to drop is maddening.

Do it! Promise to shampoo and comb out Billy's beard before the gig! That'll lock t up for you!

Seriously, break a leg. Hope you and your guys get the gig. I'll be rooting for you.

Also, you have to remember a promoter is not the same person as a booking agent. I am sure ZZ Top was booked through there legit agent who contacted the promoter or vice versa.. Have your agent contact the promoter. If you do not have a legtimate agent, find one. It is hard for a individual person or band to get these type gigs. a inquiry call never hurts. ya never know in this business.
