I know, for me, you know, my generation - I never would have known anything about Robert Preston's performance in 'The Music Man' if there hadn't been a film where he played the part. I just heard how great he was on Broadway way before my time.

I've learned to keep my work on the stage or on the screen.

I don't have a Jersey dialect. So when I approached the singing, I approached it the same way as an actor I approach a dialect, just as a singer.

I think you couldn't do this role or you couldn't be Frankie Valli himself unless you had a natural falsetto. And I had sort of discovered it by accident as a child or a young adult when you realize you have a special skill that you don't really have any use for you, and you just take it out at parties or to amuse your friends or to annoy your girlfriends.

I definitely worked really hard to evoke Frankie Valli, but not do a strict imitation, because I feel that a strict imitation is not as compelling to watch.

But when you get to know a character so well, you start to have insights that you can't show because you're confined to your script of your hit show.
