Surflight’s nearly month-long production of the musical “Mamma Mia” is coming to an end on Sunday, Aug. 30. Up next on the mainstage – or actually the theater’s 2020 summer home owing to the COVID-19 pandemic, a big top tent in Beach Haven’s Veterans Memorial Park catty-corner from the theater itself – is “Almost Heaven: Songs of John Denver.”

The show will open at 8:15 p.m. on Wednesday, Sept. 2. Shows starting at 8 p.m. will follow on Sept.
