"Ask what was Paul and Linda McCartney's most important contribution to music, and you just might get the answer - this album, which is also more exciting than anything Wings ever did. Professor Longhair's first live recording came about at a March 24, 1975 party hosted by the McCartneys aboard the Queen Mary in Long Beach, CA. It captures some of the excitement that Ahmet Ertegun and several lesser-known talent scouts found when they came upon Harry Roeland Byrd playing road houses around New Orleans in the late 1940s".
