Dweller is right. I do know for a fact that the University of Wisconsin Marching Band has made CDs in the past. IMO, they are a great band (I am an alumnus, so perhaps a little biased). Contact the Music dept., marching band, Mike Lekhrone (sp?) is the band director.
I think Hal Leonard Music will have what you're looking for, but I was not able to access their site. I used to work for a non-music division of this company and I know a big part of their market was in marching band music.
