A Song For Sunday - Paul Butterfield & John Sebastian - Amazing Grace (harmonica duet, 1977)

If you love blues you need to see this documentary HORN FROM THE HEART: The Paul Butterfield Story is a feature-length documentary about the life and career of legendary blues musician Paul Butterfield. A white, teen-age harmonica player from Chicago’s south side, Paul learned the blues from the original black masters performing nightly in his own back yard. Muddy Waters was Paul’s mentor and lifelong friend, happy to share his wisdom and expertise with such a gifted young acolyte. The interracial Paul Butterfield Blues Band, featuring the twin guitar sound of Michael Bloomfield and Elvin Bishop, the rhythm section of Sam Lay and Jerome Arnold and the keyboards of Mark Naftalin, added a rock edge to the Chicago blues, bringing an authenticity to its sound that struck a chord with the vast white rock audience and rejuvenated worldwide interest in the blues. The band's first LP, The Paul Butterfield Blues Band released on Elektra Records in 1965, was named “#11 Blues Album of All Time” by Downbeat.
