I have absolutely no problems with David, but I do with Alan, Phil and Chris White. Pick is verging on the border of falling into despair and sometimes says strange things we discussed in other threads and plays in tributes more.
I think it's refreshing when someone tells the truth. It shouldn't be about saying complimentary things just to keep your job.
Having said that, I've only ever known Chris White saying lovely things about Mark and speaking glowingly about his time in Dire Straits.
Pick I think it's reasonable to say has legitimate reasons to be negative.
He was a founding member, a huge part of the sound of Dire Straits. The reasons he has given in recent interviews why he left the band I have found to be quite truthful, as I experienced very similar things during my short tenure.
On from that....there is nothing illegal, or copyright connected with playing other people's songs, either on record or in concert. You have to notify the music collection agencies (like PRS and ASCAP) and a portion of your income goes to the writer (in this case Mark).
Good musicians (like Alan, Chris White etc) want to play, even as they reach retirement age. The choice is playing original music in front of 200 people in a local pub or club, or playing a cover song, which you have a strong creative connection to, in front of 2,000-3,000 in a very nice arena or concert hall.
No one here would choose the first option I think.
It's also not a cruise. I know from watching it in person, Chris White (and DSE) work incredibly hard.
