Danny Parker was a famous jazz musician before the Great War. He played in casinos around America along with fellow musician Paul Clooney. Danny may have played the piano, considering his poster features one, although it is unsure. He knew fellow performer Dean Domino but the two weren't on friendly terms. According to Dean, he was a stingy man who valued his money. His fate after the bombs dropped is left uncertain, although he was most likely killed in the blast.
According to Dean Domino, Danny Parker doesn't like to tip.
