Agreed, regarding topical humor. That's why Dreamworks and Pixar try to keep as much topical humor as possible out of their animated films. It dates them, and makes it almost impossible to reintroduce to new generations every ten years or so (as Disney has done with all of their best animated films.) That's why the sitcoms that you see being syndicated decade after decade, are the ones that, "The Brady Bunch" notwithstanding, are based on timeless situational humor..."Gilligan's Island", "The Munsters", "The Addams Family", "I Love Lucy", etc. You don't see that kind of play for largely topical shows, like "Family Ties", for example.
Folks also don't remember that Civil War Suite was kind of a dud in '79 until the corps headed south of the Mason-Dixon Line (even taking into account that the corps was struggling in the early season.) The audiences in the South ate it up, the rest of the country, not-so-much.
Bits like those in 'Black Market Juggler', and 'Thunder and Blazes', or 'Big Noise' would likely fare better.
It would be absolutely awesome to see the Bridgemen, in something reminiscent of our former glory, perform for a DCI Finals-week crowd. IMNSHO, it would take a super-version of the corps, with a special initiative to put the biggest, best corps on the field for a single-season, 1-shot, edition of the Bridgemen Alumni.
What the current Bridgemen Alumni corps does is great within the context of the alumni oeuvre, and is fine hobbyist-level drum corps, but I believe that others here are correct in stating that the Friday Night crowd at DCI would need something on a different scale to make it work.
