Um-Skit-a-Rat-Trap-si-si-do. Copyright. 1894, by Spaulding A Gray. Words and Music by Frank Addis Kent. 
I'll sing of a great musician, who plays in a big brass band, He blows on a silver cornet, and trills with a master hand; His runs on the grand piano are ever a source of bliss, And when he rehearses it sounds like this: 
Chorus. "Um-skit-a-rat-t rap-si-si-do." "There goes Casey." "After the ball is over," "My sweetheart's the man in the moon!" "And for bonnie Annie Laurie I'd lay me down," and "Trao-skit-a-rat-trap-si-si-do." 
He plays all of Sousa's marches, on Wagner he loves to dwell, He studies the latest operas, and renders the music well; At times he will start to whistle, and sing all the times he knows, It's funny to hear him, this way he goes:- Chorus. 
I think he is going crazy, on music and instruments, His fam'ly is getting worried, they say he has lost all sense; He plays from the morn 'till ev'ning, and sometimes his meals he'll miss, he won't cease from playing, his tune's like this:- Chorus.
