Elton John, Idina Menzel and Pentatonix are some of the performers who'll be helping Disneyland celebrate its 60th anniversary this Sunday night on ABC.

The two hour special The Wonderful World of Disney:  Disneyland 60 will feature Dancing with the Stars champ Derek Hough as Master of Ceremonies, and feature a history of the park, behind the scenes features, a preview of a new Star Wars attraction and musicians performing their takes on classic Disney tunes.

There also will be plenty of dancing in the special, as Derek and Disney legend Dick Van Dyke team up for a duet on "Step in Time," from Mary Poppins.  Here's more from ABC News.
