Hello. I am a reasonably decent pianist, played for about 15 years on and off. Some friends have asked me to play some piano for about 20 minutes while people are entering and milling around at their wedding. Problem is I don't have many upbeat classical major type pieces in my repertoire at the moment, nor do I have loads of time to learn new stuff, so I need some nice major pieces that will be appropriate and easy to pick up quickly.
Your suggestions would be most appreciated. Thanks.
