Unidentified Music -- Miles or not?

I'll get to the point: I'll pay $100 to the first person who can positively identify the following music sample I posted on YouTube.  It is a 2-minute 40-second part of something I recorded off the radio (in New York City) onto a cassette tape thirty years ago.  I want the complete piece.  I believed it was Miles Davis (circa late '80s) but the people at Miles' official web site say it is not.  If it's not Miles then who is it?!  It is not even one of the eight million recordings that Shazam has scanned.  Some one in this world must know the title of this piece and who performed it.

^ Thinking about this further, the fact that there is an acoustic piano solo makes me think this may not be Miles.

Just listened to the live version of "Tutu" on "Live Around the World" by Miles and it does not sound like your clip at all. The solos were done by digital synthesizer and electric guitar and the melody was the same as the album, unlike the totally different melody on your clip. The overall feel of the tune was way more energetic fusion than your clip, which adds to my feeling that your clip is not Miles.

I just listened to three different live versions of "Tutu" by Marcus Miller. each version was different, and one had lots of extra chord changes like your version. Each version had a different trumpet player too.

^ Yes, they seem to be the same break, or very similar.

I wonder if it might be The Endless Miles Project listed in my above post.

I managed to get some clues on this from someone who worked closely with Miles for a time.  He is Adam Holzman, who was Miles' keyboardist and music director from '85 to '89.  He is certain that it's not Davis on trumpet, but with at least a grain of doubt.  That grain of doubt being the possibility that it was Davis during the time he was using "an Italian keyboardist."  Another comment was, "There were lots of things coming out in the late 80's that sounded like 'Tutu.'"  That would be a strange phenomenon -- how or why would someone make a piece that somehow sounds like "Tutu" without calling it "a version of Tutu?"  Another thing that seems to get blurred when I get suggestions is that the piece I'm searching for was recorded in a recording studio -- it's not a live performance before an audience.  It could have been some kind of limited pressing given out to some radio stations for exposure and then canceled a full release of the work -- who knows?  That could be the reason why Shazam hasn't scanned it.  I could be looking for something where there were only a handful of pressings made (relatively speaking).  The question remains as to who were the people who sat down in a recording studio one fine day to make this music, have it pressed under some label or another and have it sent out and played on the radio.  

Another aspect of my search, since I've had to go this far with it, is what the make up of this ensemble is because it might provide some clues.  We have a muted trumpet which is the only horn instrument.  We have a piano, which you said is acoustic.  There is no base guitar but there is what sounds to me like a double base.  There is a drummer.  There is what sounds like strings but is that a synthesizer?  If so, that would be a modest group of only five people to make this lovely music -- not some big band.  Another question (which I don't know is practical to even ask) is: under what record label may this piece have been released.  Some labels tend to associate themselves more with certain genres of music (or musical acts) than others.
