In page Willie "The Lion" Smith:

"

Willie also belonged to a gang, and the gang had a club called The Ramblers (two members were Abner Zwillman and Niggy Rutman). Willie was one of two black men in the gang, the other being Louis Moss, who Willie referred to as a "sweet talker, who could take his foes apart". Moss later became known as "Big Sue" and owned a saloon in Tenderloin, Manhattan. Moss was his own bouncer at his club (according to Willie, Moss was 6'4" and about 240 pounds). Willie says he used to help him out by playing piano in his back room.[1]
