Silent footage. Max Moore, owner of Interstate Grocery in Helena, Arkansas, was the sponsor for radio station KFFA's "King Biscuit Time" program. We believe he shot this home movie circa 1942. In it, renowned blues musicians Robert 'Junior' Lockwood and Sonny Boy Williamson perform on the front porch of a small-town Arkansas grocery store. This is likely the earliest footage of these musicians performing together. The second portion of the clip is a 1952 tour featuring Williamson and his band. This film was preserved with a grant from the National Film Preservation Foundation. Max Moore Home Movie Collection.
