At New Orleans' House of Blues sometime in the 1980s George Thorogood invited John P. Hammond, who died yesterday, to join him onstage in a rendition of Bo Diddley's "Who Do You Love." Hammond's growling vocal and his skill on blues harp, accompanied by Thorogood's guitar, made this a memorable performance. Hammond was the son of John Henry Hammond (1910-1987), record producer and civil rights activist, who promoted the careers of Black musicians. Young John's godfather, from whom he got his middle name, was Paul Robeson.
