The Princetown Seniors are inviting others to take a trip with them on July 19 to see a performance of “Mamma Mia!” at the Mac-Haydn Theatre in Chatham.

“This mega hit is sure to have you dancing in the aisles,” says a notice from the Princetown Seniors. “Prior to the show, enjoy a buffet lunch at Yianni’s Restaurant just down the street.”

The cost is $78 with a limit of 40 people. The bus leaves the Wade Terminal at 10 a.m.
