The taller Jon's the shorter Jon,
the shorter John's name's longer.
The tall one stands on, stamps a box
to make their live-sound stronger.

The short one stands on no such thing
Though some say that he oughta
for tall Jon's taller on his box
which makes short John look shorter!

Tall Jon a bow den he requires
Short Spiers with boxes, pleases.
In short, the short Jon's long and bows
The long John's short and squeezes.

There, that clears that up…. Errr, doesn't it???
Hic... more brandy! Cheers! - HFA (Duncan McFarlane)
