Huzzah!, the new Ren Fair-themed musical from Legally Blonde songwriters Nell Benjamin and Laurence O'Keefe, will make its world premiere at San Diego's Old Globe beginning September 13, but cast member Liisi LaFontaine debuted one of the musical's new songs, "World We Live In," at a July 22 So and So's Piano Bar concert celebrating the work of Benjamin and O'Keefe. Watch the full song above in the exclusive Playbill video.

The original story takes audiences to the Kingsbridge Midsummer Renaissance Faire, where two sisters are working to save the family business from financial ruin. To save the faire, the sisters shell out big bucks for the greatest swordsman on the Ren Faire circuit, which could fix everything or be the final nail in the coffin. The new show will officially open September 25, with performances continuing through October 19 on the California company's Donald and Darlene Shiley Stage. Annie Tippe is directing.
