Joni Piano Music

[Martin Giles]

Hi folks

Martin in London here delurking once agin with a question..

Does anyone know if there is any sheet music for piano available of Joni's
songs? A big Joni fan I know is stumbling along, learning piano with the
usual classical stuff, but I think she would get a big, big boost if she had
something like River, or The Last Time I Saw Richard written out in dots
infront of her.

Can anyone help?

atb,
Martin.
