Hi Al and Di,

Thank you. What a supreme and wonderful compliment.

Yeh, it's amazing how far you can stretch the blues. It must be a testament to the sheer durability of the form. If you interpret the changes as widely as possible, I think the blues contains every one of the iconic harmonic transitions known to man: 2-5's both major and minor, 1-4's, you name it. You can even throw in a couple of blub-blubs and get away with it!
