Sorry for the late reply, Jonas.
Here is the set list from the show I attended back on March 17, 2016:
Act 1:When You Go
Suil a Run
Ride On
The Hills of Ireland
The Whole of the Moon
How Can I Keep from Singing
Amazing Grace
I See Fire
Bodhran solo (Ray Fean)
Bean Phaidin
Danny Boy
Nil Sen La
Act 2:Skyrim
Orinoco Flow
Sometimes a Prayer Will Do
Special Irish Centenary tribute: Mná na hÉireann (poem)
O Ro Se do Beatha Bhaile
My Land
Adele Medley (Glenn and Ronan)
Like an Angel Passing Through My Room
The Butterfly
Walk Beside Me
Westering Home
And if you show them enough love:
Teir Abhaile Riu
The Finale
Here's the set list from one of their Facebook posts on April 17. It's pretty similar, but some of the songs were re-ordered and Nil Sen La was removed:

I think I've seen some minor variants of this set list floating around, so it's possible it's getting tweaked a bit throughout the tour.
As for the choir, here's what's listed in the souvenir program I got at the North American tour on March 17:
- Joshua Hurley
- Ronan Scolard
- Glen Murphy
- Carl Maguire
I know for sure Ronan and Glen are still on the tour. The other two, I'm not 100% sure.
Hope this helps!
