Great post by David. Seems genuine and heartfelt.
As for the conflict between the brothers, what exactly is the heart of the it? David claims he's entitled to more money from his contribution on the first albums, Mark disagrees, and until that's settled, they really have nothing further to talk about?
After David left the band, both MK and John played in David's first record, so what happened when David left DS wasn't the reason of their nowadays situation.
I remember that when "Sultans of swing" compilation was out, David was very angry as MK management left him out of the royalties he would had to get paid by the songs in which he plays from his days with DS, he was angry not only with the management but also with MK as obvioulsy MK knew about it. As far as I know when DS signed the contract they did as a band so the four of them would had signed that right about royalties, maybe that royalties had a date limit, I don't know, but I know DK sued his brother, or his brother managemnt by this reason.
Also there is the MK first guitar chapter. MK gave MK first guitar to David and David about ten years ago tried to sell it in a place like Christie's, and MK got to know about it and bought his own guitar, we don't know if directly or through lawyers.
