Tubby the tuba

"Tubby the Tuba is a delightful animated program children of all ages will enjoy. Dick Van Dyke plays the voice of Tubby, a sad tuba in a famous orchestra. With all the wonderful songs the orchestra performs, Tubby only gets to play a few notes. With a desire to play more, Tubby decides to join the circus. Befriended by Mrs. Elephant (Pearl Bailey), Tubby becomes an instant success, and travels throughout Europe playing to sold out crowds!"@en
