Well, after several years - the original piano music for "Ace in the Hole" is now available! 2nd verse and all! http://yorkspace.library.yorku.ca/xmlui/bitstream/handle/10315/24462/JAC004001.pdf?sequence=3

In case that link goes away, here are the 2nd Verse:
" The more you go around,
good old New York town,
you'll find that what I say to you is true.
They'll meet you with a smile,
but you know all the while,
that they're trying to spring something new.
The things they're always telling,
of lemons that they're selling,
and hundreds that they spend in buying cloths.
Ev'ry one knows that they're lying,
it's the aces do the buying,
that drum them from their heads down to their toes."

and 2nd Chorus:
"Some of them send ... and that's their ace in the hole" (same as first chorus)
They tell you of money that they may have spent,
and then they will flash a bank roll,
They'd be in the bread-line,
without clothes or a dime,
if they lost that old ace in the hole!
