A random memory surfaces. I was working on the final of the video & directing class one year, where we had to make an exactly 20 or 30 second long ad, I don't remember which. Had to source a product, write, direct, shoot and edit the video for it. (Making a very short video is an art. Another year I filmed and edited a three hour long play!)
Anyway. I needed music for it and messaged my older brother like: "Could you noodle something slow and hopeful on the saxophone for me?" He said yes.
