Some people refer to her as the Queen of Country, and that's all well and good. In fact, Dolly Parton is one of the savviest songwriters working today -- she was country-pop a decade before country-pop was cool, and turned to bluegrass a couple years before T-Bone Burnett helped revive the genre's popularity. Ultimately, however, gays love Dolly Parton because of her message and her spirit as much as her music. "I think it's because they know that I'm different, too, and it took a long time for me to be accepted," she said about her gay fans on Joy Behar's talk show two years ago. "We should allow people to be who they are, and love them as they are....I always say, 'Well, sure! Why can't they get married? They should suffer like the rest of us, too.'" There won't be any suffering at Wolf Trap, as Dolly takes the stage this Sunday, July 31, at 8 p.m. Wolf Trap, 1645 Trap Road, Vienna. Tickets are $35 to $60. Call 703-255-1900 or visit wolftrap.org.
