SOUSA AND THE SLOPERPHONE
Pa won't be beat! He's not going to play second fiddle to any Yankee living. If he'd been brought up to it he'd have been a great musician I'm sure - pity he never learnt. Since Sousa's splendid band has been over Pa has evolved an instrument of tort- ahem, music, which makes the vaunted Sousaphone sing very small. Assisted by a few talented amateurs he gave a concert the other day. Mr. Sousa, F.O.S., kindly conducted and complimented poor Pa on an excellent performance. The wind was, perhaps, if anything a leetle too strong for perfect balance, still he had no doubt the Sloperphone had a great stare [?] before it - off the Newfoundland banks, as a fog-horn! -Tootsie.
I'm guessing that Sloper wasn't the first to consider the Sousaphone an instrument of torture!
