Wow...thank YOU, sir!
Just curious, are you listening to the "official" album, or the compilation of all the various takes of the material issued over the years that I made for you? In general, I prefer the things on the official album, but the Columbia-issued
"Shadow of Your Smile", is really, REALLY special, I think.
And speaking of bottles (and other ingestables), the take of "Shadow: that didn't get released until 2003 is one of the most beautifully disturbing examples of near-incoherency triumphing over itself that I've ever heard. That song must have really stirred up a lot of stuff in him.
In the interest of having a "jazz" connection for the unconvined, it should probably should be noted that the orchestral arrangements were done by Bobby Scott. The story of Marvin's decades-long obsession with these tunes and these charts, and how he came to seek solace from perfecting his performances to them in a time of deep depression and despair, is told in the biography Divided Soul by David Ritz. A great book, fwiw.
No matter, it's some deep stuff, I think. Hell, MARVIN was deep.
