The most successful black vocal duo of the 60’s was Sam and Dave. On stage they were electrifying. Off stage they rarely spoke to each other. Most of the 70’s weren’t good for the two performers but interest in their music was rekindled in 1979 after the Blues Brothers covered their hit “I’m a Soul Man.”  The 45 can now sell for $25.00 but the Sam & Dave album, “Hold On, I’m, Comin’,” released by Stax Records in 1966, can sell for $150.00 today.
