Dumbo - It's Casey Junior
Disney

It's Casey Junior comin' down the track
Comin' down the track
With a smokey stack

Hear him puffin' 'round the hill
Casey's here to thrill
Ev'ry Jack and Jill

Ev'ry time his funny little whistle sounds
(Toot toot)
Ev'rybody hurries to the Circus grounds

Time for lemonade and crackerjack
Casey Junior's back
Casey Junior's back again
