Haskell Robert "Cool Papa" Sadler (April 16, 1935 - May 6, 1994)[1] was an American blues singer, songwriter, and guitarist.
Born in Denver, Colorado, United States,[1] Sadler moved to California and worked in clubs in the San Francisco Bay Area starting in the 1960s.[2] He played a number of times at the San Francisco Blues Festival. Sadler wrote "747" as recorded by Joe Louis Walker,[3] and "Yesterday" recorded by Tiny Powell.[1] In the 1970s, he recorded as "Cool Papa" for TJ Records.[1] Cool Papa proved to be a guiding hand to Gene "Birdlegg" Pittman, then a new arrival in the Bay Area, and Pittman played alongside Sadler for 13 years.[4]
He developed diabetes, and had a leg amputated in 1990. He died, aged 59, in Berkeley, California, in 1994.[1]
