In a reply regarding the sheet music... We were given the parts just for this concert, however I still do have a copy of piano 1. Unfortunately, I do not know where the parts for piano 2 are now... Try looking for A.Peggie on prestomusic.com, scoreexchange.com or boosey.com
It sounded cool! I tried to find the sheet music on the following websites. But, I could not find it, so I sent an email to you. I really appreciate it!
