Dave,
I had my variation 4 push button in on the dinosaur i30 years ago, but that is the only one and yet it works. Ha ha.

I've never heard you before this post. If I did it was very little.

It made me listen to Billy Joel. His phrasing reminded me of Ray. Lots of musicians playing piano and doing vocals have a bit of Ray in them especially if they grew up in the 50's and 60's.
