Upbeat piano pieces?

[steven_thebear]

Hey guys,
I've been asked to try and find some classical pieces for piano which are reasonably upbeat and happy, and I'm wondering if anyone has any clue about pieces to be looking at. From my research I've come across Mozart's K 521 (

), which is pretty similar to what I would like but I resent piano duets (playing them at least) and there's no one I could play it with unfortunately. I really like that Mozart piece however, and I'm wondering if Mozart had any other similar pieces of that nature for solo piano? Unfortunately, being more of a romantic/modern pianist (aspiring), I'm a bit rubbish with naming baroque and classical pieces so sorry about that! Thanks for your time, it'll make a nice change from Rachmaninoff's Prelude in C# Minor and Chopin's Ballade No.1! BTW, it doesn't necessarily need to be limited to Mozart!
Thanks

Louis Gottschalk did some happy stuff.  The whole suite Golliwog's Cakewalk came from is fun.
Debussy Children't Corner is a lot of fun.
Enrique Granados wrote some cheerful things.
