3/2 law actually...not square law (or quadratic if you prefer)
It is actually pretty simple. A single ended triode will yield all harmonics but with a monotonic decay where each subsequent harmonic is significantly lower than the one before it...with 2nd of course being the most abundant.
Perfect FETs actually behave in some cases better, like a Class A push/pull output stage... the problem is that you will never have perfect FETs and so you will get plenty of distortion in the real world.
A good simulation paper is the following:

Thanks. I have a Beethoven recording by James Boyk of which I am fond. I will read through in detail and see whether Boyk is a better EE or pianist :)
