Here's how I learned it:

In a town not far from here
wherehere where they sell the schnops and beer
ther's a lady whose arm is in a sling.
Oh she's the worst you ever saw
for she nearly broke my jaw
she's my cockeyed consumptive Mary Jane.

Mary Jane, oh Mary Jane,
oh she's the worst you ever saw
for she nearly broke my jaw
she's my cockeyed consumptive Mary Jane

Oh she's a dandy she's a daisy
she knock kneed and crazy
bowlegged pigeon towed and lame
oh she's the worst you ever saw
for she nearly broke my jaw
she's my cockeyed consumptive Mary Jane.
