Itzhak Perlman and Yo-Yo Ma play "Humoresque" (Suzuki Book 3).
I found this while idly cruising YouTube, looking for Suzuki pieces that I have played or intend to play. I am going to have to go back and work on my "Humoresque" to put a little more feeling into it. Well, actually, I think Perlman and Ma might be putting a little too much feeling into this, but I love it, and I am going to try to emulate it.
One of the comments on YouTube is "I didn't know this piece could be played that well."
