From 1992 -1994 it was on ITV during the day on Saturday's before Baywatch and the rest of the evening stuff, you might remember that? I think it showed on channel 5 in late 1999 or early 2000 at earliest when it was going downhill.
I probably did watch it on ITV then. I certainly watched Baywatch, Knightrider, Gladiators, etc.
Reading up about it on Channel 5, apparently they added old-school Batman-style "pow", "thwack", etc. to it
