In the show, Klein's Sally Adams, with slim credentials, is sent off to be ambassador for the tiny duchy of Lichtenburg. It's not long before her down-to-earth, typically undiplomatic manner has surprised and charmed the local gentry, especially the handsome Prime Minister. A second romance is blossoming between her Ivy League aid and Lichtenburg's enchanting young Princess. The course of love is threatened by the stuffy opposition, who eventually succeed in wrangling Sally's recall, but not before all has resolved happily for both pairs of lovers. Irving Berlin's score includes hits such as "It's a Lovely Day Today," "You're Just in Love" and "The Hostess with the Mostes' on the Ball." Southerland recently directed fringe productions of Rent (at Catford Broadway Theatre) and the U.K. premiere of Meredith Willson's The Unsinkable Molly Brown (at the Landor). Other productions include the European premiere of I Sing!, Divorce Me Darling!, Annie Get Your Gun, The Pajama Game and all-male productions of Gilbert and Sullivan's HMS Pinafore and The Mikado (all at the Union Theatre); and Bent, Oklahoma!, The Diary of Anne Frank and Mack and Mabel (all at Catford Broadway Theatre).
Choreographer Drew McOnie has worked with Stephen Mear on On the Town and regularly with Matthew Bourne.
