Willie "Hip Linkchain" Richard 
Linkchain was an American Chicago blues guitarist, singer and songwriter.
His stage name was in deference to his father's nickname, Linkchain, which was due to his habit of sporting logging chains around his neck, and the boy's childhood nickname, Hipstick (in slang, a really and tall hipster, usually wearing skinny jeans, because of their resemblance to sticks).
By 1959, Linkchain had formed his own band, the Chicago Twisters, with Tyrone Davis as frontman. 

Theodore Roosevelt "Hound Dog" Taylor 

Taylor was an American Chicago blues guitarist and singer.
Taylor had a condition known as polydactylism, which resulted in him having six fingers on both hands. As is usual with the condition, the extra digits were rudimentary nubbins and could not be moved. One night, while drunk, he cut off the extra digit on his right hand using a straight razor.
He was known for his electrified slide guitar playing (roughly styled after that of Elmore James), his cheap Japanese Teisco guitars, and his raucous boogie beats. In 1967, Taylor toured Europe with the American Folk Blues Festival, performing with Little Walter and Koko Taylor.
In 1971 Bruce Iglauer used a $2,500 inheritance to form Alligator Records, which recorded Taylor's debut album, Hound Dog Taylor and the HouseRockers. The album was recorded in just two nights. It was the first release for Alligator, which eventually became a major blues label. Iglauer began managing and booking the band, which toured nationwide and performed with Muddy Waters, Freddie King, and Big Mama Thornton. The band became especially popular in the Boston area, where Taylor inspired the young George Thorogood.
He told writer Bob Neff the way he would like to be remembered: 'He couldn’t play shit, but he sure made it sound good."
Growing up in the Mississippi Delta, his childhood was not an easy one. When he was only 9 years old, his step father supposedly packed up all of his things in a brown paper bag, stood in the doorway with a shotgun, and told Hound Dog to "cut out". That's the way the story goes anyway. From info I've gathered from people who knew him, this story may or may not be true. But he did go to live with his older sister around that time in his life (Randy Meadows).
