The Sliphorn King of Polaroo Teagarden Animation

 godfather Walter Lantz, whose industry renown and public name-recognition sometimes approached that of cartoondom's other Walt, headed a house with inhabitants like Woody Woodpecker, Wally Walrus, Buzz Buzzard and Andy Panda. In his catalogue Lantz had a special category: the "Swing Symphonies," which sampled modern Big Band sounds and welcomed input from contemporaneous artists like trombonist Jack Teagarden, and the more classically oriented "Musical Miniatures." Standouts included The Greatest Man in Siam (1944), Sliphorn King of Polaroo (1945), Apple Andy (1946), Bandmaster (1947) and Kiddie Koncert (1946).
In the Sliphorn King the basic premise is that a trombone player named Jackson falls overboard and washes up on the island of Polaroo. The trombone solos are played by Jack Teagarden, the great jazz trombonist and there is a wonderful song the denizens of the island sing about Jackson, called, naturally enough, "Jackson, Sliphorn King of Polaroo".

The only other musician in the reed section I recognize is the darkhaired Ernie Caceres on clarinet.

Jack Armstrong Blues Teagarden Jack 1951

Teagarden could actually play in a way that appealed to him. It relied heavily on using unusual slide positions and aalso on his ability to bend notes with his unusually flexible embouchure. His style is generally considered to be literally "inimitable."
Teagarden had a mechanical bent and a life-long interest in tinkering with things, and he invented the water glass mute effect, in which the bell section of the trombone is removed and an empty water glass placed over the end of the instrument tubing (of the mouthpiece section). The effect is a stifled, plaintive sound which makes the instrument sound even more like a blues singer.
