What is wrong with Don having a big concert for his 70th ? My only problem with this is that I can't go to it! He had no problem selling out big arenas on his solo tour and I'm sure that his main "angle" for this is to have a good time and to celebrate his achievements with actual fans.
Yes, money is a factor here but its the same with all of us.
If you don't agree with what Don is doing, that's fine but don't make him out to be some cold, money obsessed person. If you have a problem with this, write to Irving and see what he says!
