What if there were a Broadway musical based on the discography of Ace of Base? Hey, if it happened to ABBA, it could happen to everyone's favorite Swedes from the 90s. If I ran things, I'd simply call it The Sign , an epic romance set against the backdrop of the "turbulent yet carefree 1990s" (as quoted from my hypothetical Playbill). Perhaps we could be treated to an emotional rendition of "Don't Turn Around" in which our hero and heroine are on the verge of a teary-eyed break-up. Maybe our heroine doesn't approve of her man's lifestyle as a jewel thief and con artist and breaks out into a rip-roaring version of "Living in Danger," complete with choreography by Mia Michaels or Travis Wall. Just throwing it out there. And if it does happen, just remember who came up with the idea first. H.P.M.
