Jason,
It's basically a show-biz story. It's about Peter Allen, a gay Australian entertainer who rose from humble beginnings in the outback of Australia to become one of the best selling-entertainers in New York in the 80's. He was also a prolific song-writer ( writing such pop hits like I Honestly Love You, I'd Rather Leave When I Am In Love, I Go to Rio, and even an Oscar-winning song , Arthur's Theme, etc.). He was mentored by Judy Garland and became Liza Minnelli's first husband. The show itself, woven around his many songs which seem autobiographical as they are placed in the show, highlights his extraordinary joie de vivre.
And Hugh Jackman is incredible and extraordinary in presenting this portrait onstage. He is a true triple threat - sings with equal gusto and tenderness, dances like the best there is, and shows the audience what a very fine natural actor he is. He is also supported by an excellent cast, with Stephanie Block as Liza, Isabel Keating as Judy and Jarrod Emick as his companion, Greg.
Go see this very entertaining show - it's worth it! If only for Hugh's great adlib and audience interaction moments
