Lazy River Armstrong br This clip from 1962 shows Louis Armstrong visiting a riverboat where he hears a jazz band play and joins the group. The amazing part is that two members from his famous Hot Five are playing in this band. There is Louis with Kid Ory on trombone and Johnny St. Cyr on the 6-string banjo. The other musicians are leader Harvey Brooks on piano, Alton Redd on drums and Mike Lay on trumpet .
