Second time was a warm car, going from third to fourth gently, lowish revs, straight road. Less of a panic, hasn't happened since.
I'm going to have a look at the fluid as the first-stop to detect the problem,
I might want to buy some of that there really good synthetic modern stuff before I do ...
Recommendations here??

Sounds suspiciously like the seals are going, either in the master cylinder or the slave cylinder. Not sure the price premium on synthetic fluid would be worth paying against the normal cost of a good quality DOT4 brake fluid. For the amount the clutch is used and the heat (not) produced, it wouldn't really benefit you any.
