Bob Dylan put in a mighty fine performance of 'The Night We Called It a Day' on the penultimate David Letterman show last week, despite looking profoundly uncomfortable for every single second that he wasn't singing. When Bob's on the telly you never quite know what you're going to get. I wouldn't have him any other way.
Here are a couple of Bob's previous appearances on the box from a few years back, each of them a triumph. Many happy returns of the day Mr Dylan. See you in October.
