Claire Bloom and Billy Zane are heading to London’s Haymarket Theater to appear in “Six Dance Lessons in Six Weeks,” Richard Alfieri’s two-hander about the mutual life lessons learned by a widow and her flamboyant dance instructor.Resounding flop ran on Broadway for less than two months in 2003 in a production that starred Polly Bergen and Mark Hamill. A more favorably received 2001 production in L.A. starred Uta Hagen and David Hyde Pierce. Arthur Allan Seidelman, who helmed both the Rialto and L.A. incarnations, directs the West End production. The Haymarket’s current tenant, “Seven Brides for Seven Brothers,” shutters Nov. 18, cutting short a run that was to have extended to February. “Lessons” is skedded to run Nov. 27-March 3.
