Jarrod Emick, who had previously been announced in the role, was replaced when final contract terms could not be agreed upon. Emick recently played Peter Allen's lover in The Boy From Oz on Broadway, and first shook up musical theatre when he took home a Tony Award as Joe Hardy in the most recent Damn Yankees.

"Both the producers of All Shook Up and Jarrod Emick's representatives believed a deal would be made," said lead producer, Jonathan Pollard. "However, in the end we simply could not agree on the terms. The entire production team regrets that Jarrod won't be with us, as we have great respect for his ability and wish him well. We also feel incredibly fortunate that we didn’t have to look very far for his successor. Cheyenne Jackson, who was hired as his understudy, is a star on the rise whose talent and assets will have a prime opportunity to be discovered..."

Jackson recently appeared in a developmental summer 2004 run of the new boy-band musical spoof, Altar Boyz. His Broadway credits include Aida (Radames standby) and Thoroughly Modern Millie (Jimmy understudy, Trevor Graydon understudy). Regionally, he appeared in West Side Story (Tony), The Most Happy Fella (Joey), Hair (Berger), Grease (Danny), Carousel (Billy Bigelow), Children of Eden (Cain), Anything Goes (Billy), Kismet (The Poet) and the title roles in The Rocky Horror Show and Joseph and the Amazing Technicolor Dreamcoat.

The show will feature such Elvis Presley classics as "Heartbreak Hotel," "Burning Love," "Love Me Tender," "Can’t Help Falling in Love," "Jailhouse Rock," "Blue Suede Shoes," "A Little Less Conversation," "Hound Dog," "Don't Be Cruel," and of course, "All Shook Up."

Broadway previews begin Feb. 20, 2005, at the Palace Theatre. Opening is set for March 24, 2005.
