Back in '86 Don not only was a regular on FTV he also composed the music, wrote the theme song and performed it for the Saturday morning cartoon Galaxy High. (If you haven't noticed everything he was involved at this time was aimed towards children:)
(Note: Both shows were produced by Don's friend Chris Bearde)
Here is a brief descripition of the show from the video box:
Blast off to the outer space high school where the students come in all shapes, sizes and every color of the rainbow! At Galaxy High the junior class president has six hands. The local pizza parlor is as close as the nearest satellite and when the science teacher get mad he melts! Join two earthings exchange students as they encounter a crazy collection of cosmic kids from all over the universe.
