OK. This kinds doesn't count, but this area has been a little dead recently, so I will post this.
I went to the river and took a couple photos of my friends running their boats. Came back and needed a video of the images out that same day. Finished the photos and know it needed a little music.
I plugged in and went with the first sound that was loaded up. I played through one time writing the chord progression as I went. Then a quick time through the bass while I called my drummer to come over. One time improvising a lead with a real loose sound, and the drummer came through the door in the last few bars. He ran it two times through the drums, trying to play to my ghosted timing. From plug in to out the door on a USB stick was 53 minutes. Ended up missing my video deadline by 9 minutes.

Love it man, the world needs more of this!
