Apparently there was no full theme available with 'good' quality. The full version includes music from the title screen first ~10 seconds.

This was originally music to be played on the menu screen of on the cancelled game 'Fighting is Magic' by Mane6. Now working on Them's Fightin' Herds.

Music probably created by RC88
