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'm not talking about just Donald Trump's politics - it's what he's brought up. It's a real conversation. We're just people trying to fall in love as nations and human beings. We need therapy, man. The world does.

For me I look at a group like Queen or AC/DC or the Beastie Boys. There was melody within what they did. There was a certain style with what they did. I think it is coming back.

[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 have a tendency to sabotage relationships; I have a tendency to sabotage everything. Fear of success, fear of failure, fear of being afraid. Useless, good-for-nothing thoughts.

On social media and [in person] I hear stories of how a song like "Home" helps. Whether it's a guy overseas coping with missing his family or something deeper and terribly dramatic. Somebody once told me that ["Home"] is the song they listen to when they go to the cemetery to visit their child that passed away. It gives them hope. At the end of the day, that's all what I want to offer people.

A lot of artists talk about getting out of their comfort zones and being the most proud of their newest album. But it is true for me. I rethought a lot of what I do.
