Just listened to an interview with legendary music presenter Paul Gambacini and he said he once heard the Dire Straits version of Private Dancer.
Hal and Alan always said the band played the song with MK and as far as I understood they recorded it with him, at least in a demo version. And they said the version was fantastic and very similar to Tina's, specially the bass and piano sections.
Tina has said, she loved Mark's vocal/version of Private Dancer, so, it must be in a vault somewhere, another one for the rarities box set?
Tina had this to say about Private Dancer:
"I never had to stoop to that in my life," she wrote in her autobiography. "But I think most of us have been in situations where we had to sell ourselves, one way or another.
"When I gave into Ike, when I kept quiet to avoid an argument, when I stayed with him despite longing to leave, that's what I was thinking about when I sang the song, the sadness of doing something that you don't want to do, day in, day out. It's very emotional."
