Photo Flash: Neil Patrick Harris and Stephen Colbert in Rehearsal for COMPANY!

The New York Philharmonic will present Stephen Sondheim's groundbreaking Company, with an all-star cast led by Neil Patrick Harris, on April 7-9, 2011. The award-winning musical will be produced and directed by Lonny Price, who directed and co-produced last season's SONDHEIM: The Birthday Concert!, and will be conducted by Sondheim specialist Paul Gemignani, with the original orchestrations for a 35-piece orchestra by Jonathan Tunick.

Among those joining Harris in Company for the New York Philharmonic will be Patti LuPone as Joanne, Anika Noni Rose as Marta, Martha Plimpton as Sarah, Jim Walton as Larry and Stephen Colbert as Harry.
