Donny Hathaway [1972] - You Had To Know - Unreleased

This is song that Hathaway wrote for Cold Blood for their 1972 album 'First Taste Of Sin' which he produced for them.  It is believed that this track may have been a demo he recorded for them to prepare for the recording session.  It has never been released, and you need to listen to it fast as it has already been removed from Soundcoud so who knows how long it will remain on YouTube for, it was only posted a few days ago (4th Dec)?

This is so soulful.  Makes you wonder what else was left in the can?
