Brilliant choir at St. Francis Xavier's church Gardiner Street, Dublin 1. I know they are mainly a church gospel choir but I'm pretty sure they do other types of music also. I think they reconvene after a summer break next week or the week after.
Well, this [broken link removed] hasn't sung U2, but they do sing Gospel and have even been known to "do Britney"!i still haven't found what i'm looking for.....
