I think Sheryl Crow has got a number of good songs, although might be prejudice because I like the way she looks!............But, I can't imagine her trying to sing the female part of Gimme Shelter.
Then, it's Lisa Fischer who I think is amazing, because the first time I remember hearing Gimme Shelter and all of us being blown away was the Steel Wheels concert in Syracuse in 1989...........And, then the times I've seen them since them, that song has been the concert highlight as well with her being the highlight of the song. Damn - what a voice!
