Lot's of folks have been waiting for the October schedule (including me for later in the month). Ray is usually very good about updating it--he's probably dealing with hurricane related stuff or something.
If you call the bar when you get down there, perhaps they can tell you who will be playing during your stay. I have called the night and found out who was playing so I could decide whether or not I wanted to go.
CLynnJones, as SyracuseWolvrine said, Tuesdays tend to be extra crowded (cast members get in free). Most nights, it tends to be pretty hopping, with slightly larger crowds on Friday and Saturday. Sundays and Mondays seem to be the slowest days in my experience.
Have a great time! Try to catch Scotty and Ray!
