Hi nelly lots of good bands that play around newry are:
Sugar town road
Also heard good things of Peach and manouche swing, think they're all a bit further north but I'd say nearly all bands travel far and wide!
If you look at th canal court band listings that's a good indication of local bands! Would also recommend electric avenue from drogheda I think, a little dear but with the euro price works out about the same as the northern bands!
