Is Barenboim on Beethoven coming back?

To mark the 200th anniversary of Ludwig van Beethoven's birth in 1970, Daniel Barenboim and Christopher Nupen collaborated on a 13-part series about the man and his music. 

Much of the material they shot was never broadcast and, until recently, the footage lay dormant for half a century. Now, as the 250th anniversary is celebrated, the series has been resurrected in its original form.
