Song called "Willa"...need artist and lyrics

My brother used to have a crush on a girl called "Willa". I remember that there was a song by the same name but I can't find it? Do you know it?

Only one Willa song to be found , it's about a dog??( no lyrics available)
Done by Peter Himmelman , on the "My lemonade stand "( children)album ('04).
Then there is a Willard song by Bran Van 3000 from the " Glee " album.
