My dear friend "RadDudeski69" has uploaded the above mentioned youtube-videos of this song.
And in the remarks he has added a quote (most presumably from PC):
"(I have) some friends out here in Geneva called the Silvano Bazan Trio. I've sat in on drums with them, they've played at my house, my birthday, and I sang 'Teach Me Tonight' on their CD."
This explains the pretty simple story how this collaboration came together. Sometimes things can be quite simple.
