songwriting-and-performing:

Did you spend a lot of time working on the lyrics to the songs, or was it more spur of the moment?

I spent a fair amount of time editing the lyrics and allowing the songs to kind of evolve. It’s a hard question to answer because anytime there’s anything worthwhile, it certainly “feels” like it happened on the spur of the moment, but it’s a composite of lots of spurs of the moment, hopefully. And over time, you catch up with those, and then you have full set of lyrics you’ve thought of and you feel comfortable singing.
