From:
Six Concertos pour Orgue et Orchestre
de G. F. Handel.
Arrangés pour Orgue Seul avec Points
d'Orgue par Clément Loret.
This is not a baroque piece, it is a romantic adaption of a baroque composition.
The Larghetto (III. Movement) was taken from the Concerto Op. 7, 1
I took the Solo-passages in the Allegro (IV. Movement) from the Presto of the d-minor-Suite for Harpsichord.
