1978 Harvest Label Original. Front Cover Photo By Linda McCartney. “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. Highlights Include The Rollicking "Mess Around," And The Standards "Stagger Lee," "Everyday I Have The Blues," "I'm Movin' On," And His Hits "Mardi Gras In New Orleans" And "Tipitina." The Lack Of Instrumental Credits Prevents One From Praising The Lead Guitarist By Name For His Playing On "Everyday I Have The Blues" And "I'm Movin' On," But He And The Rest Of The Band Still Do Well Backing This Legend.” Bruce Eder, All Music Guide.
