Glad to hear that you and Mrs Knopflerfan enjoyed the concert! I downloaded Joe's 2009 concert at the RAH from YouTube and just like you, I was impressed with his guitar playing and I enjoyed a lot of the songs, especially Sloe Gin, but after a while I began to feel that everything sounded very similar, unlike MK's music which is varied.
I'm sure you bought the blue-ray just for Eric, though, didn't you, Knopflerfan!
PS Have a good time on the 27th. I will be thinking of you all and wishing I was there with you!
