Who were the Tishman twins?

Answer 1

There is a reference to the Tishman twins in an old folk song, "Shake Hands With Your Uncle Max" by Allan Sherman. It goes: Shake hands with your Uncle Max, my boy
And here is your sister Shirl
And here is your cousin Isabel
That's Irving's oldest girl
And you remember the Tishman twins
Gerald and Jerome
We all came out to greet you
And to wish you welcome home Although there maybe some twin siblings named Tishman somewhere in the world, Gerald and Jerome appear to be fictional.
