Experience-Playing the Kolintang with one hand

I have had the unique experience of playing the Kolintang with one hand. The piece I was required to play is one of Mozart's most famous symphonies of all (I forgot the name, ITS IN GERMAN!!) which was very difficult to accomplish with one hand. Lesson to be learned, never play the Kolintang with one hand. It's also quite tiring for your lone hand. :)
