Scott, I had the pleasure of working with Hank Thompson. He was in town for a Louisiana Hayride Reunion and stayed at the motel where I was playing. He sang all his big hits with me playing PSR2000. He had never seen an arranger and was pretty impressed that I could cover all his songs.
He died a couple years after that, but at the time his voice was every bit as good as it ever was.
Back when I was in Arkansas, my band opened a show for Ray Price. He was so stoned that two guys had to help him to the mic. I thought there was no way he was going to sing. He sort of slurred a few words of introduction, but when he started singing he never missed a note for an hour and a half. Then they helped him off the stage where his weed was waiting for him!
My friend played piano with him for a while several years back, but Ray developed throat cancer and they cut the tour short.
Between Willie and Ray, makes me think about taking up the wacky weed!
Back to the subject - Ron Crites has been around a long time and handles that gear very well. I pretty much did the same thing with Midjay, but of course used a keyboard controller so the one-legged dance wasn't necessary.
I'm interested in checking out the Midjay Pro when they get the bugs out. (I'm sure there will be some). Chances are the only move I'd really be tempted to make though is to Korg PA4X if and when it arrives.
