Once Upon A Mattress is the hilarious adult version of the story of the princess and the pea, set to music, of course. The show has music written by Mary Rodgers, book by Jay Thompson, Dean Full and Marshall Barer, who also wrote the lyrics. But if you thought you knew the story of 'The Princess and The Pea,' you may be in for a walloping surprise! Carried on a wave of wonderful songs, by turns hilarious and raucous, romantic and melodic, this rollicking spin on the familiar classic of royal courtship and comeuppance provides for some side-splitting shenanigans.
