As the Irish say, Jayzus!
First, any reasonably competent Irish band has been booked for the last nine months or more. You want not just one, but two?
Second, it's hardly worth the effort to unload the sound system for a 15-minute set.
On top of all that, you're asking them to play essentially for free? On the one night a year they're guaranteed a paying gig?
I made a good faith effort, with no luck. Most musicians laughed in my face, yet somehow the organizer managed to book someone, and I admit to being a bit curious to see what dregs he scraped up.
If I didn't already have a gig in Elsah, I'd stop in to see.
I might even celebrate by drinking Jamieson while wearing orange, just to confuse things.*
It's time to change the towels.
* gold star to the first person, besides my sister, who can tell me why this behaviour would be confusing.
