It was great to play for a live audience on a stage.

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'm kind of happy to know there may be some kid or teenager now who might never have had the chance to see my Broadway performance, but gets a taste for what it might have been like now, because they can see Clint Eastwood's film."

I approach the singing kind of like with dialect thoughts in my mind. I have to sound like this on certain things to give that Frankie Valli flavor.

It was a surprise to me and a happy accident that it was such a skill [natural falsetto] - a latent skill and that there was a way to exploit it. And it was a key to playing great role Frankie Valli in such a huge show.

I think Frankie Valli did everything right. He kept singing. And you also have to remember, he was confined to a certain society, which was this sort of like - the wrong side of the law kind of society of Italian guys from the streets of Belleville, New Jersey. So he found his way.

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.
