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 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.

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.

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 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.
