Sonia Friedman is aiming to produce James Lapine’s tuner tribute “Sondheim on Sondheim” at a West End venue yet to be confirmed in spring 2011.

Friedman told Daily Variety that the project is still in early stages of development but that she plans to entice a rolling cast of major musical theater names to the London incarnation by casting a succession of strictly limited engagements over the run.

The show, originally produced earlier this year by Roundabout Theater Company at Gotham’s Studio 54, features songs from composer-lyricist Stephen Sondheim’s back catalog and one specially written new one, interspersed with video interview footage of the composer.
