We are playing the music on guitars, violins, mandolins, bodhrans, etc... Sounded great! Kind of one of those whoever shows up with an instrument kind of things...
As far as arrangements, I'm not sure what you mean... The proprietor of the cigar shop is a new kiltie and certainly doesn't mind us bringing in patrons!

He and KiltedSurveyor are good friends and therefore, I think it was a no-brainer to have it there...
I'll bet they have some grand ceilidhs in and around the Big Apple!! Congrats on your 1500 posts, by the way!
