I have seen them in concert since their first visit to the USA, back in 2006. They have had 3 tours, and I've been at each. I have every CD and DVD. I was 2nd row, center stage this last concert. That video includes two former members. The redhead is Orla, and the blonde with short hair is Meav. They are no longer with the group. Lisa is the brunette (who is not in that video) and Chloe is the young lady.
Left to right in that video:
Haley (guest appearance for that concert), Chloe, Orla, Meav.
Orla and Meav have been replaced by Alex and Lynn.
I actually met Chloe (who is my favorite) and Alex this past Friday night. They are so sweet. Chloe will sit there and talk talk talk. We both talked about Ireland (where she is from and where I visited). Hard to believe she is only 19.
She has the best voice in the group.
I told my wife if Chloe came up to me and said "come with me", I'd be so gone. She gets a kick out it. lol
Mairead is the fiddle player in the group. She is really good.
