This sparkling arrangement opens with the Casavant's principal chorus, followed by a lighter section with flutes and principal 4 on recit and positif. The final verse features principal and reed ensemble. I like the crispness of the staccato chords that are possible with this set.
A version of this arrangement is published in the Diane Bish Organ Book, Volume 1. However, there's a youtube performance in which Diane plays an extended version. I have attempted to recreate her extended version in this performance. It's truly classic Diane Bish, full of energy and showmanship. I had great fun recording it. Enjoy!
