Hanrahan I can't imagine why you would wish to sing that song but I reckon it would be quite tricky to sing it while inebriated. Perhaps you had better go to this link for the "full" lyrics http://www.stlyrics.com/lyrics/thewizardofoz/dingdongthewitchisdead.htm and print out a copy as you may need it if drunk especially for the quick tempo high-pitched Munchkin' voice parts like the line "she's gone where the goblins go" below - below - below...
"Wake up, the Wicked Witch is dead. She's gone where the goblins go, Below - below - below. Yo-ho, let's open up and sing and ring the bells out. Ding Dong' the merry-oh, sing it high, sing it low. Let them know The Wicked Witch is dead!"
