"So I says to myself" redux

[James A. Landau]

In Gilbert and Sullivan's _Iolanthe_, first performed 1882, there is the
Lord Chancellor's song:


When I went to the Bar as a very young man
(Said I to myself---said I)
I'll work on a new and original plan
(Said I to myself---said I)
I'll never assume that a rogue or a thief
Is a gentleman worthy implicit belief
Because his attorney has sent me a brief,
(Said I to myself---said I)

which is not the phrase under discussion, but not too far from it,  either.

For "sis boom bah", also in _Iolanthe_ , we have the Peers'  march

Loudly let the trumpet bray!
Tantantara!
Proudly bang the sounding brasses!
Tzing! Boom!
As upon its lordly way
This unique procession passes,
Tantantara! Tzing! Boom!
