Gilbert & Sullivan Light Opera performs

WHAT The Gilbert & Sullivan Light Opera Company of Long Island presents "Ain't Cha Got Music? The Big Broadcast of 2011," a celebration of music from the 1920s and '30s. The annual concert fundraiser for the company features lead vocalists from past Gilbert & Sullivan productions and the 10-piece South Shore Syncopators dance orchestra led by Ray Osnato. You can dance to the music made famous by the likes of Eddie Cantor, Al Jolson, Paul Whiteman and the Boswell Sisters, along with a "radio announcer" to introduce the singers and move the night along with some between-song banter.

WHEN | WHERE 8 p.m. tomorrow at Ethical Humanist Society, 38 Old Country Rd., Garden City
