He really does have to play more solo stuff live though....different versions of songs do, IMO give them a different life and energy.
I agree, he doesn't really try and mess with the original arrangements too much - however maybe that's a good thing. How many times have we heard this from other artists and they end up murdering their own song?
I haven't listened to Driving Rain for a while now, there are a couple of tracks I don't think I'm ever going to 'get into'.. but my opinion of the album these days is more lenient than it used to be!
