Surprised nobody has mentioned the Kosciusko Cornet Band.
Early lineup was supposed to be all sons of Civil War veterans but that changed over time. Notable for having several female members before it was cool. More than one Charlie Musselwhite kin, near or far, one suspects.
The elderly gentleman seated at the far right of the 2nd photo is bandleader Dr. George Washington Crowder (1840-1921.) A Civil War bugler and survivor of Picket's Charge if memory serves.
Two “Charles” band members mentioned in the photo but, if we have them correctly, both were married with children. That one fellow seated two over from Doc Crowder does look like he's marching to a different drummer tho.
