Lindsey's Tusk songs

[squealy]

Does anyone know or have any guesses as to how much the other members contributed to Lindsey's Tusk tunes? I know Mick drums on "What Makes You Think You're the One" and "Tusk," and John probably plays bass on those tracks too, but are they on any of the other songs? Most of the other drums and bass sound like Lindsey could have done them. Did Christine and Stevie contribute anything at all? I don't think that's even Christine playing piano on "What Makes You Think..."

I actually get the impression that Christine and Stevie don't do anything on Lindsey's "Mirage" or "Tango" songs either, although John and Mick at least seem to be backing him up on most of those.
