I heard my Dad (Irving Levine) sing this...I believe from his days at City College (in NY City), likely not long before WWII. Or at NYU after WWII? (he was born in 1914). I don't recall if he specified the number 3...or just Jolly Consumptives.
Here is how I recall it:
"Oh We're the Jolly Consumptives -- Um Cha, Phoey! (3 throat & spitting sounds). Repeat this first section. "And when we get well again, we'll raise the same old Hell again. For We're the Jolly Consumptives -- um, cha poey!"
Does anyone know this version? And is there more to it?
