The oldest brother Joe Green (1892-1939) was as well known and sought after in the recoding business. Joe received national acclaim when he toured with John Philip Sousa's band as a featured xylophone soloist from 1915 through 1919. Not only a xylophonist, but also a percussionist and timpanist. Nat Shilkret and the Victor Company used Joe extensively for recording dates. he was also timpanist for the Victor Red Seal Operatic recordings.
The Green brothers played in hundreds of groups in recoding studios and on radio airways. Their most notable group was the Green Brothers Novelty Orchestra (mid-20s to early 30s) in which George and Joe, along with their younger brother Lew (1909-1992), a guitar and banjo player, performed the soundtrack for the first Disney cartoons, Steamboat Willie, The Opry House, and Skeleton Dance.
Joe died in 1939 of complications following an operation. George retired from music shortly thereafter to pursue a lengthy career as a cartoonist from his home in Woodstock, New York, until his own death in 1970.
