This is an excerpt from Charles Callahan's wonderful Partita on Adeste Fideles.... I play this nearly every year on Christmas Eve. I've toyed with learning the whole Partita, but parts of it always send me running (chuckle)
SW strings, coupled to GT, SW to SW 4'
Gt Principal 8, Rohrflute 8 CH strings and HohlFlute 8 coupled to Gt
Pedal Subbass and Pommer 16, add Resultant on last chord
