Google News dutifully reports to me daily if it finds any mentions of "Michigan Marching Band". In mid-summer it isn't very exciting, but sometimes interesting/funny. So, look what it found on e-bay: Halftime Classics! And look, nobody ever opened the album, and it somehow traveled all the way to California. My favorite part is that it is listed as "rare".
When I see this album, I think of a LOT of stories. The first one that comes to mind is the Alto Saxes were too loud so GRC had each of them remove a sock and use it as a mute. I think I'll stop right there.
