Celtic Woman, the PBS sensation, returns for 2007 in A New Journey: Live at Slane Castle, Ireland. Most of the elements return as well: vocalists Chloe, Meav, Lisa, and Orla; fiery fiddler Mairead; music director David Downes; chorus and orchestra. New for this show is New Zealand vocalist Hayley Westenra, a picturesque outdoor location, and an almost entirely new song list.
