Breakfast was suspected in the harpsichord concertos of Bach arrangements of lost concertos for one or more melodies instruments. By studying the solo part to some of the pieces could be reconstructed as oboe concertos. The results were sometimes so convincing that, for example, BWV 1055 and BWV 1060 now listed almost exclusively in this version. Marcel Ponseele and Il Gardellino make two more concerts for discussion here.
