People, people, people. Marching bands? Marching bands? You are defining trumpets as things used in marching bands? Come on, come on. Ska bands. The trumpet is an (forgive the pun) instrumental part of any ska band. Think of a good song. Does it have a good horn lick? Of course it does. That's the horn section, you see. Makes sense. And in the horn section, what do you find, but... trumpets! So, please. Do the baby some respect. Because ska bands are very cool. Much cooler than marching bands, anyway.
