To the piano I went, to start finding chords and seeing if the melody that had flitted through my mind with the words worked. Some words were scratched out to suit the beat of the song. More chords added, arrows drawn to move sections around. A bridge riff jotted in. A tempo determined, changed, fixed upon.
Played it in fits and starts through the day until the feel was right. Played it at band rehearsal last night and have some guitar pieces to add to it now.
And 'Knock' will make its debut on Sunday morning.
