Reformed Irish folk supergroup CLANNAD will be celebrating St Patrick's Day in style tonight (17MAR07) with a sold out Kilkenny show and a TV special. The IN A LIFETIME hitmakers reunited for their first full concert in 10 years in January (07) and now they're celebrating Ireland's national day with a Kilkenny showcase after a week of shows in Derry and Dublin. Meanwhile, a surprise reunion that took place at singer MOYA BRENNAN's Rotterdam concert last October (06) was filmed by Irish television network TG4, as part of a documentary about the beloved group. The film is slated to premiere tonight in Ireland, while footage of the group's comeback concert at Celtic Connections in Glasgow, Scotland will also be broadcast.
