About A St. Patrick's Day Celtic Sojourn: WGBH presents the sixth annual A St. Patrick's Day Celtic Sojourn with Brian O'Donovan in two locations this year. Last year, the show sold out quickly at the beautiful Sanders Theatre in Harvard Square and we will return there on Friday, March 18 at 8pm. This year will mark the first time the show will play at the Zeiterion Theatre in New Bedford; Saturday, March 19 at 8pm. This year's version will feature a dynamic young five-piece band from Ireland called Téada, who will be joined by a truly iconic singer and accordion player, Séamus Begley, from the Dingle Peninsula in County Kerry. Also on the bill is Irish American singer-songwriter Carol Noonan, accompanied by guitar gods Kevin Barry and Duke Levine. And we are delighted to introduce uilleann piper, Tiperarry-born, Michael Cooney. (Uilleann pipes are the Irish form of the bag pipes.) As has become a tradition for the show, dancers and some very special surprise musical guests will also be added.
