I suppose the first and the last options were right? It ended up being the second song of the first act, with Caitriona's An Cailin Alainn (on computer so no fadas) opening the concert. But it was the first group song of the concert.
Well Congratulation's to the one voter!
I am surprised so many of you and I

have voted it as second act first song.
I am not surprised that it opened the show, I just thought since it's new Era it would be different.
I could of added in second song first act.
In old Celtic Woman concerts Dulaman would be a second act first song!
