When you look at sort of pop stardom now, some of these singers, it seems like the idea of them was created in a marketing meeting, and then they just found someone to sort of fulfill that role.

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.

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.

I think one of the ways that these young singers got started is that they would end up in clubs. And a lot of them were mafia owned. And so there was almost an unspoken kind of mafia sponsorship, which is just a very interesting part of that area's music history.

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.
