Sondheim on Sondheim heading for London?

Rhydian Roberts may well have let the cat out of the bag about a production of Sondheim on Sondheim coming into the West End.  On BBC Radio 2 he revealed that the show (which ended a limited engagement on Broadway in June 2010) will be playing in London at the beginning of October.
 
Roberts is due to appear in a new touring arena version of Jeff Wayne’s War of the Worlds with Jason Donovan at the end of November, but said that he was " due to go into a Sondheim show in the West End in October for a short stint."

Sondheim on Sondheim is an intimate portrait of the composer in his own words and music. It uses exclusive interview footage to give the audience an inside look at his personal life and artistic process. It would be the perfect production to round off his 80th birthday celebrations.

According to the official Stephen Sondheim Society website this news has also been confirmed by Sondheim  favourite  Maria Friedman. No official announcement on the transfer has yet been made.
