Surflight Theatre’s biggest hit during its 2019 season was “Mamma Mia,” a jukebox musical based on the songs of ABBA, the Swedish pop supergroup of the 1970s and early 1980s.

So Surflight decided to bring it back in 2020. Indeed, after COVID-19 messed with the season and the theater had to cut back to two mainstage summer shows, now performed under a big top set up in Beach Haven’s Veterans Memorial Park, Surflight left “Mamma Mia” on the short list.
