Well before Ellen DeGeneres, Wanda Sykes, and Lily Tomlin came out, Kate Clinton was paving the way as an openly lesbian comedian. Since 1981, the self-described “fumorist” (feminist humorist) has been performing her acerbic, politically charged stand-up at gay pride rallies, women’s music festivals, nightclubs, and fundraisers. She’s also written columns for The Progressive and The Advocate, as well as two books. Clinton brings her Lady Haha tour to the Center on Halsted, 3656 N. Halsted, Sunday January 24, at 6 PM. Tickets ($40) at 773-472-6469, ext. 446 and online.
