If you missed Tir Na’s outrageously funny TRAD last season, you’ve been granted a reprieve. Gloucester Stage is reprising the show, lock, stock and barrel through the end of September. You’ll be seeing director Carmel O’Reilly’s hilarious father and son odyssey, trekking from pillar to post in search of an heir. It matters not that father is a hundred or so and son is twenty years his junior. They’re determined not to be the last of the line. Billy Meleady and Colin Hamel are the irascible geezers and Nancy E. Carroll is everyone they meet along the way. Think Beckett on hallucinogens. You’ll laugh yourself silly. Then just when you think it can’t get any nuttier, a nifty ending will touch your heart.
