I don't remember how to play it, but I remember what it was. I'm Heaving You Out. It was very mid-sixties sounding, sort of faintly bluesy, but very faintly. I keep threatening to sort of revive it, but I don't know if I'll get around to it. It has changed a little over time, but for many years now, like say the last 20, it's been pretty much exclusively lyrics first.
Different songwriters operate differently.
Most of the songwriters that I'm acquainted with go the other way. They start out with music and then they find words that seem to want to go with it. But for me it's about the words, and the music is a vehicle to carry those words. I've compared it before to writing music for a film because you have ideas, you've got imagery, you may have a story or characters in the song lyrics that need support from the music and for me the application of the music to the words is based on those considerations. It's the guitar that I get the music from, and I love music.
