Yep, that's my plan, but I didn't know if there was a technical term for this sort of situation. If there isn't we should make one up. :)
A fiddle-trip? A hemi-half-y? A tipple-lent? How do you tell everyone to be sure to observe the whoopee-splortch if you don't have a word for one?
Clementi called. He said that, yes, we can use his theme, but only if we don't write anything as good as the Magic Flute overture with it. (Apparently, the original piano sonata has been overshadowed quite enough already...)
