They’re 160 years old, and crushing it onstage

Two elderly actresses are fighting for the same stage role … in a new play, “Best If Used By,” written by Ipswich actor and author Doug Brendel, whose columns appear in the Salem News and Gloucester Daily Times, among other reputable publications.

The story was inspired by two North Shore women. Brendel worked with each of them in different community theatre productions.

“Each of them knocked me out!” he says. “They both had 20 years on me, but they had more energy than I had. Not to mention talent!”
