I agree, Jim .
many musicians who play in sessions have never played for a dance in their life .
[imo]some of the dances now being danced ,are also not always danced to the best rhythym for dancing.
eg Seige of Ennis to jigs,I know there are people on this forum who will disagree with this statement.
and again we must just agree to differ,but I find the side stepping to jigs ridiculous,in my experience the best tunes are Rattling Bog,Spanish ladies,Girl I left Behind me etc.[Just a personal opinion,from having danced,and watch dancers trying to step Seige of Ennis to jigs ]
