A quote from the Radio Times to clarify things:
"Knopfler's days as a soundtrack scribe (Local Hero, Cal, The Princess Bride) are sadly under-explored, but where the programme really scores is in the off-the-cuff, front-room performances and charmingly prosaic stories about the origins of songs and riffs ("I fiddle about with the amp")."
There is more but you'll just have to buy it!
