MIKE POST was my all time favorite theme writer (Rockford Files, Hill St Blues etc).
My all time fav TV theme is his NYPD BLUE, the blending of the music with the track sound of the subway was just pure genius (IMHO)
Gigantor looks lik a tick. I never sw that show. The only time I think I heard the name was when Owen Wilson was calling Ben Stiller "Gigantor" in "Night at the Museum"
