Hampton was a featured artist at numerous Cavalcade of Jazz concerts held at Wrigley Field in Los Angeles and produced by Leon Hefflin Sr. His first performance was at the second Cavalcade of Jazz concert held on October 12, 1946 and also featured Jack McVea, Slim Gaillard, T-Bone Walker, the Honeydrippers and Louis Armstrong. The fifth Cavalcade of Jazz concert was held in two locations, Wrigley Field in Los Angeles and Lane Field in San Diego, July 10, 1949 and September 3, 1949 respectively. Betty Carter, Jimmy Witherspoon, Buddy Banks, Smiley Turner and Big Jay McNeely also played with Hampton. It was at the sixth Cavalcade of Jazz, June 25, 1950 that precipitated the closest thing to a riot in the show's eventful history. Lionel and his band paraded around the ball park's infield playing ‘Flying High’. The huge crowd, around 14,000 went berserk, tossed cushions, coats, hats, programs, and just about anything else they could lay hands on and swarmed on the field. Dinah Washington, Roy Milton, PeeWee Crayton, Lillie Greenwood, Tiny Davis an Her Hell Divers were also featured. His final Cavalcade of Jazz concert held on July 24, 1955 (Eleventh) also featured Big Jay McNeely, The Medallions, The Penguins and James Moody and his Orchestra.
