Together with singer and songwriter Frank Grain, Ernest Stokes was half of the minstrel-show type duo called Mustard & Gravy, who trim records in the center of the twentieth century for a number of little labels, among the Gotham Information in Philadelphia, where they documented “End up being Bop Boogie” in 1950, which later on became a rockabilly number in the hands of Don Hager as well as the Hot Tots, in NEW YORK. They’re displayed with one music, Rice’s “Circus Parade,” within the Library of Congress’s Folk Music in the us series, Vol. 13 (“Tracks of Years as a child”) in 1978.
