I'm definitely obsessed about artists and the type of music and the playing and the tone and all that kind of thing - I'm not obsessed about what the best Beatles album is. I just think if The Beatles are great, they're great.

In the early-'60s, when you look at that period of time - up to the mod time - when everybody was wearing skinnier suits and skinny lapels and skinny ties - that came out of the States, and that was quite cool.

There's always peripheral things that you like that you don't know, but starting with whatever his British influences are, are some of my favourite artists, and the American things are what I grew up on as well. In the end, for me, it's those foundations of the music business - those things that are a lot of the foundations of what music today is. You can hear a bit of all of those things that we talk about in almost all music today.

In my old age, my mind gets more open, and I listen to so many different types of music and I guess that all reflects in my work.

There are so many artists who get to my age that get comfortable and just stick in a groove, and I really don't want to do that.

I saw an interview with Keith Richards. He said, 'How else could a kid in Dartford suddenly connect with and understand what Muddy Waters is singing?' There's a cultural difference, but there's just something in that music that subconsciously or internally you just understand; it just makes sense.

The whole nostalgia thing, and just sticking with what you always liked and what you know and not taking a chance on something or expanding. I think especially after a certain age.
