From a song sheet (broadside) at The Library of Congress American Memory Collection:

POP GOES THE WEAZLE. (sic) NO. 3.
H. De Marsan, Publisher, 38 Chatham Street, N. Y. [no date]

Queen Victoria is very sick,
Napoleon's got the measles,
Sebastopol's not taken yet;
Pop goes the weazle,

CHORUS: All round the cobbler's bench,
The monkey chased the weazle,
The priest, he kissed the cobbler's wife,
Pop went the weazle.

A penny for a ball of thread,
A penny for a needle,
That's the way the money goes;
Pop goes the weazle. CHORUS

My wife, she is awful sick,
The baby's got the measles,
Sally's got the whooping cough;
Pop goes the weazle. CHORUS

Johnny Bull, he makes his brag,
He can whip the whole creation,
Why don't he take Sebastopol,
By Pop goes the weazle. CHORUS

Mayor Wood has put the rumsellers through,
The Maine Law's a sad evil,
We cannot get our toddy now;
Pop goes the weazle. CHORUS

[The line "Sebastopol's not taken yet" would seem to date this version to 1854-55.]
