Hey Nancy!

 NB> the line is the sort that would catch your attention

Yes it is.  Good thing I was half paying attention.

As we speak I happening to have it on and there is a commedian doing a really
unrelatable commedy routine that I could easily have missed.

 NB> After which you appreciated the song even more

Not really but it did help explain why it never matched the premise of the TV
show ... except maybe the "got youself a gun" line which is something that
gangsters feel is a required tool of their trade ... or so I am led to believe.

 NB> but the other cartoon studios also used classical, often from
 NB> opera, musical selections

I recall "Bugs Bunny" doing an opera(s) way back when.  I seem to recall it
being small clips from different operas designed to more or less match the
action.  Elmer Fudd was hunting wabbits if I am not mistaken.  There was one
scene with the "Barber of Seville" which is the only thing that comes to mind
at the moment.

Looking down at the bottom of this reply I see that we're getting very close.

Life is good,
Maurice
