This instrumental blues was originally created and developed as a vocal piece of music by the American blues singer Charles Isaiah Ross (1925-1993). He recorded it in 1953 under the title "Mississippi Blues", and again in 1956 when it was retitled "Cat Squirrel". It was reworked by Eric Clapton and recorded for the album "Fresh Cream" (1966) and lateron reworked by Mick Abrahams for "This Was".
