ceejay, I believe that whatever religion's prayers are said before a parliamentary session does constitute the promotion of that religion over other faiths. And because it is a parliamentary body's duty to represent and govern people of all faiths and none, I feel it is wrong to use prayers in this manner.

However, we aren't talking about a government body regarding this organization, so there are no church and state issues here. Comhaltas is just a nonprofit organization for the promotion of Irish arts, language and culture. There are gazillions of them around the world, and many of them use religious services common to their communities, to promote their arts, language and culture. Which is why this is all so silly.
