I didn't know until this morning that Chuck Panozzo, bass player for prog rock band Styx, was gay. According to his Wikipedia entry, he came out back in 2001 as both gay and seropositive. Since I've put up bands on QMF because they had a queer lead singer, why not because of a bass player?
I also learned on Wikipedia that Styx's biggest hit was "Babe," which I just can't stand. So here's "Come Sail Away," which is, like, one of the best songs ever.
