As Lughnassadh arrives, it just so happens that the Summer Olympic Games conveniently coincide with the traditional time for sports in Ireland dating back to before written records. This inspired me, for better or worse, to start with a concept of some sort of grand march to honor the tradition of athletic competition in the style of modern opening ceremonies, albeit with a bit less pizazz due to the simple fact that I can't conjure up a full orchestra.
Musically, this is one of the more challenging things I've created, since it relies on my very rusty trombone skills, and some of the notes that are needed are strictly speaking not in the range of the instrument I had available. For those nutty enough to try to record this, I'd recommend either electronic instruments, or re-transcribe the lowest and highest parts for trumpet and tuba.
