The Cadillac Ultimate Broadway Experience Sweepstakes began April 8 and will run through May 30.

Now in its fourth year, the nationwide contest invites entrants to vote for their favorite leading musical theatre actress, choosing between four beloved performers: Angela Lansbury, Patti LuPone, Bernadette Peters and Chita Rivera.

One sweepstakes entrant will be chosen at random on June 1 and will receive two tickets to each of the four Tony Award-nominated shows for Best Musical and two tickets to the 2008 Tony Awards at Radio City Music Hall on June 15. The prize package also includes transportation to and from New York City and four-day/three-night night hotel accommodations.

Over 27,000 people entered the 2007 contest. Last year's winner attended each of the shows nominated for Best Musical — Curtains, Grey Gardens, Mary Poppins and Spring Awakening — as well as the 2007 Tony Award ceremony.
