They did 5 shows at the Venetian from November 22 to 30, 2013. Those were Mairéad's first CW shows in the US.
Sometimes Mairéad posts her photo of the CW ad inside the Las Vegas airport from that time. Unfortunately, that was about 4 years before I knew about them!

At the show in Las Vegas last night, Mairéad said "Viva Las Vegas!" when she spoke in the second half! I think she really likes it here!
