My joke, which isn't really a joke, is that there will be one of two tours: the tour for the album that does well, or the tour for the album that stiffs.
One time Robert Plant was set to check into the same room after I checked out, so I removed every light bulb and ordered up a bunch of stinky cheese and put it under the mattress.
So it was just a case of getting a bunch of songs that I had been writing for years but hadn't recorded together, and the result was My Own Best Enemy.
The only thing that's a little tricky about it is sometimes people assume that if it's a new song, it's a reflection of what you're feeling or going through now.
