From Steve's notes "This one was fun to write. The title was actually suggested to me by a good friend as a name for a new band I was forming. Although a different name was chosen, the idea stuck with me, and when a friend came to me with a question about someone they were trying to figure out romantically, it just fit." Mona Lisa has that mystical smile that many songs have been written about, but this is one with a twist. You figure it out.
