Good one, that, Kat.

Of course, I confess that after a long session of sitting (listening to singers or even singing along), I can be quite refreshed by a stirring round of "The Noble Duke Of York," complete with all its "When they're up they're up, and when they're down they're down, and when they're only halfway up they're neither up nor down" excercises!

That'll keep me awake for at least another half hour!
