Joni is a true bad ass.

When some people come in contact with her music, it totally alters their life, Wainwright says.

I was totally in love with Joni Mitchell, Nash says.
So, of course, it would be emotional.
We spent a couple of years together and I was on cloud nine.
The end of our romance left a little to be desired, but I loved Joan so.
She has done so despite the harsh nature of some of the songs she has written about them.
Nash says one reason the men have been so forgiving is because you cant argue with the truth.
And the truth is often not very flattering, he says.
Most people would be thrilled to even be mentioned, or know that Jonis music is about them.
Thats especially true, given her songs erudition.
Nash has compared her work to Shakespeare.
I believe she will be seen in that light, he says.
Krall also likens Mitchells songs to drama.
There are so many ways to interpret them.
Many of the artists involved maintain a deep friendship with Mitchell.
Old, and new, friends whove seen her lately say she is improving dramatically.

Its astonishing, and great, that she has forgotten that she smoked!, he says.
That three-letter word yet speaks volumes, he says.
Because you know damn well that shes looking and experiencing 360 degrees.
