Eve, the Book of Genesis tells us, was formed from a rib from Adam, but the all-male vocal group Celtic Thunder followed Celtic Woman, whose ladies had been a roaring success for three years by the time the men got going, in 2007. The two groups in fact share a brain-parent, Irish producer Sharon Browne. But the men are hardly playing second fiddle. By 2008 they had already completed a US tour of 50 cities. They’ve since become a regular PBS attraction, and one former member, Damian McGinty, has gone on to star on “Glee.” This year they released their 10th CD, “Mythology”; on Tuesday, they’ll be performing live at the Orpheum Theatre in support of that album.
Speaking on a conference call with the group’s music director, David Munro, Browne explains that “Celtic Thunder was originally going to be called Celtic Man, and I actually had the concept for that one first. But I had been working with large numbers of male orchestras for over 20 years on stage, and I had a handful of boys at home, so frankly I was sick of men, for a while.” She adds that she would have gone for Celtic Man as a name, but her business partners objected, so the group became Celtic Thunder.
