The Manhattan Transfer Meets Tubby The Tuba (1994)

"The Grammy-winning Manhattan Transfer presents an incomparable vocal and orchestral performance which raises the benchmark in children's music and entertainment. They tell the story of Tubby the Tuba, who of all the brass instruments in the orchestra plays the lowest notes. He thinks other brass have more interesting music to play. Tubby just plays OOM-PAH. He wants to be like all the others. In each of his four adventures, "Tubby the Tuba," "Tubby at the Circus," "Tubby Meets a Jazz Band," and "The Further Adventures of Tubby the Tuba," he sets out to see if he can find something more interesting to do. While Tubby does find his own special melody, he also learns that his OOM-PAH makes him unique." (allmusic)
