Not surprising that memories are somewhat hazy that far back. Having been there many times I just do not recall Apollo ever being a dance bar! As I remember it was a small space with a small bar on the left as you entered and a sort of zig zag catwalk on which the boys did their stuff. The rest of the space was seating for customers. I wonder if you might be thinking of Rome Club which then was the famous Soi 4 gay dance club.
