I was probably five years old or four years and I would listen to "White Christmas," and I just thought it was the most beautiful thing ever. The musicianship and his voice and the melody of that song; it's almost like I wish it wasn't a Christmas song because I wish that you were allowed to listen to it all year.

My favorite music is '80s music which drives people around me crazy. I really love it.

The fact that there's a more open discussion about everything from feminism to racism ... I look at my two boys ... this is their future I'm talking about. When I'll be long gone, it'll be them and their kids. I know that sometimes the darkest times are followed by the lightest. Sometimes bad things have to happen for good things to happen. At the very worst, we're having very open discussions, discussions about things we didn't even know f-king existed. I talk to my friends about it and they are absolutely shocked. They didn't even know.

I'm fascinated by politics. I love watching everyone from Neil deGrasse Tyson to Lawrence Krauss to people like Richard Dawkins and Noam Chomsky on YouTube.

[Dean Martin ] had this really wonderful rich, authentic, distinct vocal style. His humour in movies [and] the self-deprecation and the coolness he had could overshadow what a marvellous vocalist in the Great American Songbook he is.

I met the [Frank] Sinatra family for a [performance] I did for his hundredth birthday and one of the first things Sinatra's daughters said to me was, "I'm so glad you make your own beautiful arrangements now."

I struggled more with my identity. Let's be honest - early on in my first records, I didn't have the power to tell David Foster or other producers what to do.
