Harry's dizzy clarinet

I wrote this (and another couple of pieces) for my friend Harry after he got his grade 8 clarinet with distinction. He told me that the trills I chose are quite awkward on a clarinet but he played them perfectly and we had great fun playing this and other clarinet pieces I wrote for him!

Composed 1986 (when I was 22) but I rewrote the piano part (which I thought was too heavy) to the version here in 1994.
