In regards to the horns, it's just a personal thing that I hate horn sections lol We've seen Southside Johnny a few times and I absolutely love him but I can't stand the horns, so I'd be disappointed to see a horn section backing Bruce full time.
I definitely agree that the sax would be sorely missed on a lot of tracks - Junglelands being the perfect example - but Clarence will be sorely missed, so it could be kind of a fitting tribute to have the rest of the band play his solos....I have no idea, just happy in the confidence that whatever Bruce chooses will be entirely respectful
