Boardwalk Empire: What Piano Song is Chalky's son playing in Season 2 Ep.4

I am not talking about the song that he plays in season 2, episode 1 which is Clair de Lune by Claude Debussy.

I would like to know what Lester is playing to the family, while Chalky is out in the woodshed in season 2, episode 4.

I know I have heard it before but I can’t place it.

Thanks if you do tell me.

No idea, but the episode is here and the music starts at 52:35

I also found this youtube clip containing the song (about 4:30), but I’m no help as to the title either.

“Curious Story” by Peter Heller.

Thank you very much, all of you!
