The Pewter Plough Playhouse’s gala celebration on New Year’s Eve features the final performance of the musical stage show “September Song,” a celebration of theater founder Jim Buckley’s 100th birthday with 40 songs from the Great American Songbook.

The performance will be followed by live cabaret music starring Yoly Tolentino and Dave Manion, plus a buffet, desserts, “bottomless” Opolo champagne, party surprises and more.

Versatile cabaret singer Tolentino sings with Sklark in Los Angeles; she’s making her third Cambria appearance.

The evening starts at 8 p.m. Monday, Dec. 31, at the theater at 824 Main St. in Cambria’s West Village. For tickets ($125), call 927-3877 or go to www.pewterploughplayhouse.org.
