A friend of mine plays it - same chorus but different verses (including the lines you mention). I don't know where he got it from, but the two verses he does are:-
Gonna take my girl to the dance tonight Gonna spin her round, gonna treat her right (can't remember the 3rd line) I sure didn't mean to start that fight
Every tooth in my head is solid gold Make that guy look awful old I brush my teeth in diamond dust I don't care if the bank went bust
