The Chicago company of Wicked will host a cabaret performance, Defying Inequality, to benefit several organizations working for gay and lesbian civil rights–including the right to same-sex marriage. The organizations are Equality California (the state where voters recently passed a law overturning same-sex marriage), New York’s Empire State Pride Agenda, New Jersey’s Garden State Equality, and the Vermont Freedom to Marry Task Force. The concert will feature members of the casts of Wicked and Jersey Boys, the Chicago Gay Men’s Chorus, and others. There will be silent and live auctions of memorabilia from Broadway musicals and Broadway in Chicago shows. Mon 1/12, 8 PM, Park West, 322 W. Armitage, 312-559-1212 or, $30-$50. Doors open at 7 PM.
