The following are songs (or song fragments) that are not yet fully realized.

Arkansas

This song reminds me of a style Michael Penn would employ: a lilting melody over a dominant seventh. The lyrics offered in the tab are just ideas.
It would work nicely as an overture for "Garden".

Here is a tab for the guitar part and here is an mp3.

Mulligan Stew

This song is only really started. It needs lyrics. I seems, to me, quite like a song that would be in "The Music Man."

Here is a tab for the guitar part, and here is an mp3.

Steampunk Overture

This harmonic-rich 14-bar "overture" ends on a G chord, and is a good optional lead-in for a song that perhaps starts on the same. For instance, I think it is a nice prefix for Keychain.
