Lindsey versus Stevie (UH-oh!...)

[Ghost_Tracker]

Okay so here's a question that I've been meaning to ask for awhile -
Does anyone else besides me have trouble telling when it's Lindsey
singing and when it's Stevie singing, on the album "Tusk?"
I know that he spent a lot of time in the studio on it in
post-production - Arranging it and all that - is it possible
that there were places where he took out Stevie's voice
and replaced it with his own? For example at the end of
"Beautiful Child" it's clearly him singing,
"I'M not a child any-more,
I'M not a child, any-more."

There seem to me to be several other places where at first blush it sounds like Stevie, but is really Lindsey, and vice-verse.
Remember, this was "back in the day" when things were - uhm - errr - "bumpy" between them.

Anyone have any insights or opinions?
