I also don't think Alan is the only example of "pissing on his chips" . In fact this is not a new phenomena for Dire Straits. Let's look at a few similar examples -
David Knopfler - we know that story
Tommy Mandel - tried to improvise
Hal Lindes - booted during early BIA sessions
Pick Withers - got fed up
Jack Sonni - "had two lovely girls" then never got invited back
Terry Williams - didn't play how MK wanted on BIA but did a sterling job on tour, wanted to play on OES tour but never got invited back
Alan Clark - obviously loves playing the DS tunes but not as obedient as lap dog Guy Fletcher
Could it not be that rather than "pissing on chips" these guys simply challenged MK in a way he didn't like, or could control??
The difference is however that all those guys were
persona non grata and had no chance of working with MK again. Whereas, as I previously stated, Alan Clark has worked with MK, albeit on small projects. So he has therefore "pissed on his chips", ie he can forget about working with MK again.
The others you mention had no chance of working with him anyway.
The more I read from you Mr Visitor, the more I wonder if you and Alan Clark have ever been spotted in the same room together at the same time...
