The first collaboration of Alan Menken and the late Howard Ashman, God Bless You, Mr. Rosewater, will be presented April 1 at 8 PM, April 2 at 2:30 and 8 PM and April 3 at 2:30 and 7:30 PM. Based on the best-selling Kurt Vonnegut novel, the musical was written in 1978. Rosewater, which debuted at the WPA in that same year, marks the 50th production in the "Mufti" series.

Jamaica will then be presented as part of the Harold Arlen Centennial Celebration. Jeff Hochhauser has adapted the book for the Mufti staging, based on the original book by E.Y. (Yip) Harburg. Jamaica, which boasts a score by Harold Arlen (music) and Harburg (lyrics), opened in 1957 at Broadway's Imperial Theatre. Lena Horne starred in the musical, which also featured Ossie Davis. Jamaica will be presented at the York April 8 at 8 PM, April 9 at 2:30 and 8 PM and April 10 at 2:30 and 7:30 PM.

The spring "Mufti" season will conclude with Jule Styne (music), E. Y. Harburg (lyrics) and Nunnally Johnson's (book) Darling of the Day. The musical is based on the Arnold Bennett novel "Buried Alive" and concerns the story of Priam Farll, "a painter who sees an opportunity to duck out of London's stifling high society by assuming the identity of his recently deceased valet." Patricia Routledge won a Tony Award for her performance in the original 1968 Broadway production. The Mufti staging will feature an adaptation by Erik Haagensen. Darling of the Day was first presented by the "Mufti" series in 1998; it is being repeated this season in honor of the Jule Styne Centennial. Performance dates are April 15 at 8 PM, April 16 at 2:30 and 8 PM and April 17 at 2:30 and 7:30 PM.
