“It’s weird isn’t it? I don’t think I’ve ever spoken about it publicly,” he said.
“I’m sick of not talking about it.”
McKenney dated Gallaher, a performer and musical theatre producer, in the ’80s while they were working together on a musical production of Pirates of Penzance.
Many years after they broke up, he found out his sister, Lisa, went on to marry Gallaher. But he didn’t learn this fact from the couple – instead, he was told by his co-stars on the set of Cats.
“She married my ex-boyfriend and is still married to my ex-boyfriend, but just has never mentioned it to me,” McKenney said.
McKenney explained he wasn’t even aware Gallaher and his sister knew each other at the time.
