Tommy did start in NYC, but then went to Japan (with the support of his father, unlike what Carlo says). Also unlike what Carlo says Tommy did in fact operate a school next to a military base (the one on Okinawa I believe but don't quote me on that just yet).

And again, Tommy sounds more like Tommy Udo in Kiss of Death as the DEA agents who hunted him said. But really he has more of an authentic Brooklyn accent.

If Tommy has an girl's voice than half the Italian guys in Brooklyn are in trouble too...
