We're a little late on this one, but: local tranny Donna Sachet made history this past week by becoming the first (?) drag queen to perform the "The Star-Spangled Banner" at a Major League Baseball game. (We cannot find any clips of her singing at Tuesday's game, but here she is performing at some pageant thingy.)
Donna http://authors.gothamistllc.com/mt/mt.fcgi?__mode=view&_type=entry&id=373346&blog_id=9Sachet, for those of you who don't know, is a favorite among the City Hall set, a noted activist, and also writes a social column for the Bay Area Reporter.
Update: Good news. We found footage of Sachet in action at AT&T Park. (Thanks, chada!)
