I'm reading an interview with Bacchus which says:
I was Gaston for a very brief time before someone made me aware that this name was already taken by one guy in Thundercats. Mind that this is not the same Gaston who was the leading cracker in Amiga Fairlight for quite some time.
Gaston left Thundercats and joined Horizon on the C64. Surely Gaston/Horizon C64 and Gaston/Horizon Amiga (who later joined Fairlight) were not two different people?
