Wow John, this is very different than most of the stuff I've heard from you on here. I like the song you've got here. The singing just before the "As sweet as you" sounds a little bit flat in spots, but that's a tough melody with the fall and rise. Nice synth solo, and the vocoder part is pretty well done.
And no, the sax doesn't sound real, but it sounds good anyway.
Your mixing chops have come quite a way since the first thing I heard from you. Well done!
Regards,
Dan
