Get those old bell-bottoms out of the closet and get ready to boogie down in Glen Cove.

The Glen Cove Senior Center is holding a '70s Mystery Theater Dinner and Dance Saturday night from 6 to 9. The event features an interactive mystery performed by actors that guests will help solve.

There will be a cash bar and, befitting a '70s-themed party, dancing under the disco ball. There also will be prizes for the best period costumes, so begin combing your wardrobe for some Carter administration-era clothes; the groovier, the better.

Tickets are $30. Proceeds will be used to benefit the center and its programs.
