Robust and challenging - or simply a slanging match? When presenter Justin Webb first joined the Today programme he said he'd be gentle and let politicians have their say. Then he changed his mind.

And after many Feedback listeners reported hearing the repeated use of "Facades" by composer Philip Glass in an array BBC Radio programmes. we finally hear from the man himself. Ahead of his installment as BBC Radio 3's Composer of the Week, Philip Glass offers his own slightly surreal insight into the popularity of this particular piece.
