As Antoinette somewhat fourth-wall breakingly intimates, the solution to my last puzzle was "Summer in the Postcard", the album Ed Rex put on in strip 187. And snatches of the lyrics to the above songs have been drifting through the strip since (I can't be bothered to point out where). The winner was 2B_or_not_2B, and as a prize I have emailed her my original cover art for the album! She has to get the music herself, of course, but hey, prize is a prize.
