Nostalgia is one thing. It's great to go and play the old songs. People know them and appreciate them. You got to give them what they want to hear.
I had to make a name up, and it came from one of my sisters; she was a fan of Frankie Laine. The 'Denny' thing, in those days, everyone had a backyard, and a den to hang out. I think I got that nickname there.
The thing is, I was more blues-oriented, more of a purist than in the pop world. That led me into a folk rock trio and to Ginger Baker before I started recording on my own.
Paul knew I could sing, write and play, and so he rang me. It knocked me sideways a little because I wasn't used to being a sidekick. That was the first time I'd been with a band with someone more famous than me.
If you end up spending more time in the studio than you do on the road, that's not a good balance for me. Because I think when you're in the studio, you need to come off the road and go in the studio and that's when you're applying your best. That's when you've got the best attitude, best energy, all that stuff.
I'm not oriented by money, to be honest. Everybody thinks we're in the music business for money all of the time. But that's not true for me.
The human voice is one of the most attractive things.
I wrote ‘No Words' and ‘Mull of Kintyre' with help from Paul. He was always like a big brother to me and a strong influence on my songwriting.
Early on I was more interested in gypsy jazz music until rock and roll came around and I listened to a lot of Buddy Holly, Eddie Cochran and skiffle singer Lonnie Donegan.
I began writing with Mike Pinder and eventually we went on to form a new band called The M&B, which later became The Moody Blues, what I would call a progressive blues band.
