I have never heard Vanessa mention anything called "Quail Dude Squaw".. I dont think there is any song called that, or if she did mention it give me a link please haha.
In this 2003 interview she mentions it as "one of the most complicated classical compositions she's ever played". Here's the link: www.nessaholics.com/pages/katia_tricia_interview_aug_7.html
I guess this was the only time she said something about this name.
This is a really great interview. Strangely enough, it's the first time I've ever seen it. I love how she was initially planning for 'Private Radio' to be the first single off the album.
