Le Boléro du Divin Mozart

The score is in a collection of pieces named:
"Nouveau cahier de pièces d'orgue"
Edition:
Cantate Domino No 3070

The composer writes in the foreword:
"...I included two humorous pieces to be handled with care. I was tired of making photocopies of the manuscript after each performance. I advise organists not to use the titles which I had to give them, but to play them as encores without giving the piece's (or the author's) names. It is funnier this way. ..."
