Máiréad announced today that she's part of a new show at Walt Disney World (that's the Orlando, Florida location) called Harmonious. It premiers October 1 at Epcot Center.
It's a nighttime spectacular which "brings a global ensemble of musical artists from around the world together, creating new interpretations of familiar Disney songs and bridging cultures and generations to unlock the magic of possibility."
I think she's just recording for the backing music for the show rather than performing live on a nightly basis.
