Days of Wine and Roses

I finished this tune this morning. I expect it will go through some changes. There are a few chord modifications, but the major idea is that the whole tune changes key (a minor third up) half way though. I first heard this kind of idea many years ago. Herbie Hancock played live a version of 'I love you' in which the tune kept the same melody but changed keys in every section. I had recorded it from the BBC radio over 20 years ago and I still have the mp3 file if any one is interested. It is with Craig Handy on Tenor and it's an absolute masterful performance. 

Check back later for corrections - I also have a rough recording of me (trying) playing it on my 5 octave keyboard. Let's see. Maybe I'll post it at some point.
