Thanks to YouTubers Quietschquatsch and Raphy013 for the music suggestion a few days ago!
Not only did Tom find this a fun tune to play, but, as you'll see, flautist Julia Riley and tubaist (tubist?) Mark Meeker decided to join in as well!
After Tom's first sight-read, you hear Julia mention another Nintendo videogame tune that she liked. That was K.K. Ragtime. A short time later, Tom and Julia played it from memory! I'll have to post the video of that moment at a later date. It was fully evolved into a fleshed-out rag arrangement, much like the second run through this tune from Super Mario World 2 in this video.
This tune was composed by Koji Kondo (近藤浩治). It is also known as "Hop! Hop! Donut Lifts" by some people, but in a concert video of Nintendo video game music at which the composer was in attendance, the title that appears clearly reads (if you read Japanese, anyway) simply "Yosshii Island Athletic Theme".
