Well, yes, for many other things far more serious, and I know it's trivial of me, but --
For Haydn's anniversary I would REALLY like to be able to use the hymntune AUSTRIA.
Prelude today, I improvised, (oh, don't dignify it with that description,) -- I noodled around, on VENI CREATOR, DOWN AMPNEY, and ST ANTHONY CHORALE.
Pretty nice, actually.
But I woud have liked to have incorporated AUSTRIA.
