The singer told Billboard magazine: “I always feel like each record is our last, but at the moment I'm in the stage where I really mean it.
“I just can't imagine how we would do another one, because we've thrown everything. When it's finished, which hopefully should be pretty soon - it has to be pretty soon - we won't have been able to put more work into it, which I guess is the only thing we can really do.”
Asked if he would feel like making another album in two years, he admitted: “I don't know. But I never know. I think it would be bad if I was like, ‘yeah, we've got 15 songs up our sleeves’. I don't have anything left.”
