I downloaded the commercial awhile ago. I did not realize the link expired. I will look for it on my PC though and upload it.

here is the promo. Anyway it features GI in it. GI was on TBS for a very long time. I think 1989 was before they colorized the first season episodes. I don't think it was until 91 they colorized them.
