Heidelberg BB is now, sadly, extinct.

London Cornet Silver Website has lapsed (although I believe the band is still going) and is no longer active.

Ohio Brass Bands should probably either be changed to Ohio Brass Arts Festival or both names should go to the same site.

I also wonder if NABBA 1998 is worth having a link to as results are available on the regular NABBA website, and Lexington BB has their own link to their own page.
