Dan; I have found the weekend does indeed make a diference at the Burren; it is very crowded and loud Fridays and Saturdays...comes of it being the most interesting bar for people who just want to drink, never minding whether there is live Irish music or not...still the crowd is usually okay, if you like crowds... but on a Monday, say, it is much quieter, so that is when the set dancers come into the front fresh from their hour of lessons in the back room and dance their stuff while the musicians play dance tunes...when the dancers take a break, sometimes some singing happens! Though those microphones are not singer-friendly...

cheers, Peg
