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'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."

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 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 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's funny - Frankie Valli's story and that advice that he was just getting from, you know, Christopher Walken's character, is very true for someone who's in a creative field.
