There seems to be two issues. One is the creak with each rotation of the pedals, the other is a minor irregularity that I feel in the power train that occurs every few turns of the pedal - which it why I thought it might be the missing link (or the missing link about to break). I can have the chain changed.
I am using old and I presume lightweight quick release skewers that came with some Mavik Aksiums, I believe, that I did not change when I last changed my wheels -- I seem to be building up a stock of new skewers! So I can swap them out easily, I think. This would be good news. I never knew that they failed.
This would also explain the busted freehub connection. The freehubs are busted (one worse than the other) and they were wobbly, but I did not think to check whether the busted freehub wobble cause bend in the quick release skewer! This is sounding very plausible!

Thanks very much indeed.
