I respectfully disagree, Pottel. Everything Mark has now he got thanks to Dire Straits, including us his fans. His guitars, studio, cars, motorbikes, houses, even his wife and family. The only reason why Mark can afford this low profile yet successful solo career is because Dire Straits came first. He wouldn't have met Kitty either in case the band never existed. I really like Mark's solo stuff but I don't really know how much of this appreciation is due to my preexisting passion for Dire Straits.
As I said before, I don't think Mark should show up at the ceremony and perform if he's not comfortable with the situation, I totally understand him for that. I also think this whole thing is meaningless, especially if they don't even pay for your expenses. However, Dire Straits will always be Mark's peak. He's written wonderful songs and produced high quality albums ever since he shut the band down but let's face it, what he created during the DS years is unparalleled. Sultans of Swing, Romeo and Juliet, Telegraph Road, Brothers in Arms, just to name a few, those are far superior to any song Mark has recorded in his solo career. Of course he has now the best studio in human history at his disposal 24/7 but I'm not talking about recording quality. Both as songwriter and guitar player Mark came up with his ultimate masterpieces a long time ago. Does that mean his solo stuff isn't great? Of course not! It's brilliant! But he set the bar too high with DS and neglecting it doesn't feel right to me.
Just my opinion...
