Editing J. Lawrence Cook (section)

==Work at B.A.B Organ Company==
Cook, along with his piano rolls, also produced band organ rolls for the B.A.B Organ Company.  In an interview with Cook in the 1970s, he was the sole arranger for B.A.B, which had produced over 800 master rolls at the time of its closure. Some of Cook's arranging for B.A.B. was never released, and is in storage in [[Virginia City, Montana]].

The organ scales that Cook arranged for included, but are not limited to:
* 46 Key Scale
* 61 Key Scale (for Artizan D band organs)
* 66 Key Scale
* 82 Key Scale
* 87 Key Scale
Cook's work is identifiable by its switching between the counter melody (trumpet) and melody sections to play the melody, and is also known for "borrowing" notes from other sections to create a more chromatic scale.

His work has also been transcribed to the three standardized [[Wurlitzer]] band organ scales by the Play-Rite Music Co. with 46-key arrangements being transcribed to 125, 48-key to 150, and 66-key to 165, and along with being heard on Artizan and converted European organs, can also be commonly heard on Wurlitzer band organs, such as the Wurlitzer 165 at [[Glen Echo Park, Maryland|Glen Echo Park]].
