I think you would enjoy this one. It's a piano, cello and violin. I fell in love with it when I heard Karl Haas explain that the melody is from an Italian folksong, starting on the beat of two. I searched in vain for a good recording, finally bought the only one available, and the sound is not great.

My latest goal - I spoke with a lady last month - is to get three local musicians to perform it soon (before the violinist moves away this summer). Our church has the finest pianist I've ever heard - professional quality. We also have a cellist (sp?) and another lady plays violin at many weddings locally. (this is a small town, and to have such talent accessible is quite rare)

I think you can hear it at this link using Windows Media. (I no longer have WM, so can't hear the link anymore. But I have the CD!)
