Temperature would be my first bet. You didn't mention what temperature you experienced during your primary fermentation. If your temperature was appropriate for the champagne yeast, then my next bet would be that your OG was not very high; therefore your yeast ate up what little sugar was present in a comparatively short time. Did you augment the bananas ...

(Whether the enzymes are actually denatured by the sulphur dioxide is somewhat unclear.)
