FYI - The KC Irish Festival is this weekend 9/4-9/6. Here's the website: http://www.kcirishfest.com
Not listed is an ongoing session from 2ish on Saturday until 5 or so by the faux cottage in the middle of the square. The session will also be on from around 1:30 to 5 (with a break from 2:30 to 3:30) on Sunday.
There are usually sessions every evening after the festival ends (around 9 or 10) in the bars at one or both of the hotels (the Hyatt or the Westin Crown Center). Again, I'll be there Saturday night.
I'm going to be at the festival and play in the session on Saturday (Dougal McGuire - aka Ardal O'Hanlon is doign stand up that evening and that's a must see).
