[MUSIC play und] It’s official, a jukebox musical based on Britney Spears hits is debuting on Broadway next summer. “Once Upon a One More Time” is scheduled to open on June 22nd… and members of Britney’s fan club will have first access to tickets. The pop star is not involved in the show’s production. Still no word on casting but a version of this show was first developed by the Shakespare theater Company in D.C. to mixed reviews. The show bills itself as flipping the script on classic fairytale characters.
