page 140 of why's (poignant) Guide to Ruby, chapter "Them What Make the Rules and Them What Live the Dream". Paij-ree plays four notes on a flute again and again, and names the gull Eb-F-F-A after that song. In the bottom left corner, drawn in red pen: a short music staff with a treble clef and four notes, the first one with a flat sign. Below it the signature "Daniel Colson".

Page 140. Paij-ree plays four notes on a flute, over and over, and a gull goes nuts. So the gull is named after the song: Eb-F-F-A.

At the bottom, Daniel Colson wrote the tune down in red. On a real staff. With a treble clef.

Before #GitHub, Daniel was a composer and played the viola da gamba. So of course.

The foxes hummed along. Badly. Foxes are not musicians.
