I can't play in sessions any more (whatever sessions there still are, not too common in sparsely-populated in Cornwall in any case) because my hearing has deteriorated too far. In over twenty years of playing just about every week, I never once experienced a bodhran player who I hadn't wanted to expel from the pub forthwith. With all due respect to you mighty guitar players, I also think that more than one guitar in a session is anathema. Irish music is tunes, not "backing." The very best session I ever went to was at Hughes' in Dublin. A dozen melody players (with one or two "names" who didn't show off!), not a drum or strum in sight, just unison playing of tunes. Grand it was!
