Lindsey's songs on Tusk

[fghering]

I was wondering if anyone could tell me whether the other members of the Mac play on any of Lindsey's Tusk songs ("The Ledge," "Walk a Thin Line," etc.). I had heard that he did everything himself in his home studio. Is he or Mick playing the drums? Is Stevie doing some of the vocals on "The Ledge"?

Thanks for whatever help you can give.
