That's a damned good point, Trask, and I'm glad you mentioned it. Performers are not usually , in my experience, the coolest people to hang around. It takes a very unusual personality to do what they do, and more often than not, a certain degree of self-centeredness.
I don't think I could count the number of times that I've been disappointed to find that an artist whose work I admire is an insecure and/or arrogant jerk - either through an interview or a personal encounter, etc.
If RD's personality hasn't served him well in his professional life, and caused him to make an ass of himself in front of live audiences, shouldn't we feel a little bit sorry for him?
