No.
Even back then tickets went on sale a few months before the show.
I think maybe Mark and John felt deflated, playing odd venues to two thirds full crowds. They then projected their own feelings on to the rest of us and assumed we weren't giving it our all.
In the end, you don't get to be a successful freelance player (like me, Phil, Danny, Chris White, Paul Franklin) unless you are extremely professional and a dedicated player. You don't sustain such a career by giving 50-75% when you feel like it.
On such long tours like McCartney and Dire Straits I had to play at 100% level on four hours sleep, with extreme jet lag, when I had a bad cold etc....
That is the job.
