I think the big size of OES tour was bad, bad idea. MK had dificult at home, he become bored on tour and later must to "run away from DS and never come back".
My hypotesis is small scale production for OES, like MK solo tour, DS could survive to today. The band could make development, go new direction, not only hold to old hits. Sad.
Because John Illsey and MK own DS name I will love if they make DS a pub band again 
Like "hobby band" 
But a DS comeback will be followed by a hugh demand from the public, so they will have to play stadiums again to reach all the people that would want to see them...
Not necessarily - remember all the demand to see the NHB and they only played about a week at Ronnie Scotts.
It's an interesting theory but apparently arguments were had very early on in the tour anyway and so I'm not sure just what difference it would have made. Perhaps the sheer scale and pressure made it like living in a pressure cooker for them?
The BIA tour was arguably bigger in terms of pressure, if not scale and Mark didn't really seem so tired on that. Maybe just a little, but we don't have many recordings from the Australasian leg. I think the final show in Sydney sounds a bit tired anyway.
His solo career coincided with a new direction his life took when he met Kitty so perhaps that has something to do with it as well. Darling Pretty - Darling Kitty.
I don't think DS should reform though. You can't repeat the past.
