The Decca Broadway release of the Duncan Sheik-Steven Sater musical features the Broadway cast — including Lea Michele, Jonathan Groff, Skylar Astin , Lilli Cooper, John Gallagher Jr., Gideon Glick, Brian Johnson, Lauren Pritchard, Phoebe Strole, Jonathan B. Wright and Remy Zaken — directed by Michael Mayer.

Decca Broadway dominates the top of the chart with four of the five slots. The hit musical Wicked at No. 1 with Mamma Mia! and Monty Python's Spamalot rounding out the top five. (Rhino's release of the 2006 Tony Award-winning Best Musical Jersey Boys holds steady in the No. 2 position.)

Along with Avenue Q, the cast recordings of Wicked, Mamma Mia! and Monty Python's Spamalot have remained on Billboard's Top Cast Album Chart for the full 51 weeks since the chart's inception.

The release of Stephen Schwartz's Wicked has topped the chart for 46 of the 51 weeks the chart has been published. The recording has dominated the spot, only being toppled by the Columbia Records two-disc "Harry" release (comprised of the recording of Broadway's The Pajama Game revival and selections of Connick, Jr.'s 2001 show Thou Shalt Not) and The Color Purple for one week each. Rhino's release of Jersey Boys, following its big Tony win, also took hold of the top slot for four weeks.

* A recent addition to Billboard's listings, the Top Cast Albums chart debuted in Billboard on Jan. 12, 2006. Stephen Schwartz' Wicked — which opened on Broadway in October 2003 (album released Dec. 16, 2003) — appeared at the top of the first chart. The chart measures sales of albums from stage musicals. Broadway recordings mostly fill the 15-slot table, but cast albums from other locales are also eligible. The addition of the chart to Billboard's 112 charts generates exposure for the genre which does not often chart on the Billboard 200.
