The press announcement does not include what songs the three shows will perform, although the official Mermaid website says star Sierra Boggess will perform that musical's "Part of Your World," and Variety reports Frankenstein's Megan Mullally will sing "Deep Love," and Catered's Faith Prince will belt out "Vision."

As previously reported by Playbill.com, the cast of the Tony-nominated Best Musical Passing Strange will perform "Keys" — the call-and-response portion of the new musical at the Belasco Theatre that features its Tony-nominated creator and star, Stew, singing, "It's alright . . ." — on the 2008 Tonys.

Playbill.com has also learned that In the Heights, which has been nominated for 13 Tonys — the most of any show of the season — will perform Lin-Manuel Miranda's "96,000," a joyous song about the hope of a lottery windfall.

Cry-Baby, also nominated for Best Musical, will perform "A Little Upset." That David Javerbaum-Adam Schlesinger song features Cry-Baby (James Snyder), Dupree (Chester Gregory II), Allison (Elizabeth Stanley) and the ensemble.

Xanadu, the new musical at the Helen Hayes Theatre based on the film of the same name, will perform Jeff Lynne's "Don't Walk Away," which features Kerry Butler, Cheyenne Jackson, Tony Roberts, Mary Testa, Jackie Hoffman and the Muses. TV watchers can also expect performances from Best Revival of a Musical nominees Gypsy ("Everything's Coming Up Roses"), Grease, South Pacific and Sunday in the Park with George ("Move On").

As previously announced, the 2008 Tony Awards will also include performances from the casts of Rent and The Lion King.
