The situation appears to mirror many UK sessions where all that is played consists of Irish music. The majority of what is played are Reels. You seldom hear a jig, almost never a slow air. If a hornpipe is played, the lilt of it is flattened out to the tempo of a reel.
I can usually join in or listen for about 20 minutes after which it just becomes a Diddley-Diddley blur where everything sounds just like something done previously.
