Desperately seeking somewhere to party tonight? Express yourself at Madonnathon, Cathyland’s 11th annual tribute to the Material Girl. Dress yourself up in your best Madge look (be it lucky star, cone bra, or Breathless Mahoney) and get into the groove as performers like Chris America, Tammy Faye Starlite, Erin Hill and Her Psychedelic Harp, and the Rhythm Knights Dance Troupe justify your love for the Queen of Reinvention in all her myriad forms. Want to live to tell about getting onstage and singing with the band? Just strike a pose, there’s nothing to it.
