Mario Lopez took the Broadway cast of A Chorus Line to Dancing with the Stars earlier this week. This weekend he hosts the taping of a line-up of performances from all of the musicals from the 2007-2008 Broadway season.  Casts will perform numbers from  A Catered Affair, Cry-Baby, Grease, Gypsy, In The Heights, Passing Strange, South Pacific, Sunday in the Park with George, The Little Mermaid, Xanadu and Young Frankenstein. The Tony Awards preview concert will air on CBS affiliates between May 26 and June 7 so you'll have to check local listings.

On Tuesday we'll get the actual Tony nominations.  Actor David Hyde Pierce, of Frasier fame and a Tony winner last year for Curtains, and actress Sara Ramirez, of Grey's Anatomy fame and a Tony winner for Spamalot, will do the honor of announcing them.
