Okay, now, here we are. The posting is in progress from the Prince Theatre concert on Friday night (3 up, and probably 3 to go). This is one of the several improvisation "demonstrations" of the evening, and , it seems, the crowd favorite (at least I kept hearing about it afterward): The "ADD Improv". Apparently now a staple for future shows. Here is the info on the YouTube post: "This concert contained several fun demonstrations of musical improvisation; this one being a collage of 5 melodies chosen by audience members. Cards were distributed with selections in the following categories: Traditional melodies, Christmas songs, classical themes, marches, and novelty tunes. The post picks up with my examining the cards selected."
