Ayotte Custom Musical Engraving accepted my submission and has recently released my "reconstruction" of Haydn's Clavier Concerto in C Major, Hob. XVIII:5. It is available here: https://www.ayottemusic.com/products/4166-haydn-clavier-concerto-in-c-major-hob-xviii-5-reconstructed-by-lenny-cavallaro/.
I am most delighted by this latest publication, as it was very much on my mind when I began the project more than nine years ago. I submit my Preface to the volume below.
