There ya go lad, I teased a little in my first message, but alison and Tinwhistlers mutha have really given you the best lists. From those you will be able to contribute to any session, while you get comfortable with the lay of the land. I would add one very small caution, and that would be to pay attention to the etiquette (sp?) of the group you are in. Some sessions are very serious affairs, while others are just good craic. I occassionally sit in on one where they don't allow the dancers in the same room with the players. I don't know you, so please don't take offense at my next comment. Remember that it is about the music, not about you being as good or better as the others. Treat "the aul ceol" with the respect it is due and you will enjoy yourself tremendously. Most players love the music and thoroughly enjoy helping others as well.
