When I'm performing, the music included on the night depends on the crowd I'm playing too, and requests are not a problem, even if it's a song I may not know very well I have had entire audiences sing the songs for me as I play along, it's all part of the craic.
Here are some (definitely not all ) of my regular songs just to give you a taste of what to expect, and I am always adding new material to my repertoire. If you would like a particular favorite played at your event, no problem, if it suits I can learn it for you (I love a challenge :-)
