Thanks. I was having a hard time looking for the lyrics. By the way, the mp3 i found is this.

O, I am Doctor Eisenbart, Twil-li, wil-li, witt, boom boom!
I'll cure your ills with healing art, Twil-li, wil-li, witt, boom boom!
My patients never can complain, Twil-li, wil-li, witt, boom boom boom!
They leave without an ache or pain, Twil-li, wil-li, witt, boom boom!
Sing toriay sing toriay! Twil-li, wil-li, witt, boom boom boom boom!
Singtoriay, sing toriay! Twil-li, wil-li, witt, boom boom!
Repeat 2X
