At first, I thought your screen name stood for "Raff Plays the Piano" but then I saw the "y" at the end of Raff and realised otherwise. Do you know about the composer Joachim Raff, though? He has some nice (if you're into Romantic salon-ish music like Thalberg, Sauer, and Herz) pieces, and for a big finish I might suggest his Don Giovanni Fantasy...certainly you've heard Liszt's, but Raff's is more concise, much easier, and still pretty effective (though, one may argue, maybe not as much as Liszt's...). At least for those who trash Liszt for "over-indulgent flashiness" and so forth, Raff's paraphrase is more elegant and subdued, though it still does end with the famous Don Giovanni aria from the second act.
Anyway, I dunno if that interests you or not. It'd be a neat, obscure piece from an obscure composer that has some oomph and good Mozart melodies to boot. I usually don't hand out sheet music, but if you really want to I can slip you a copy (PM me) to look over. I don't have any recordings, though!
