Marching Bands #1

Over a year after I originally posted this puzzle, I saw a Marching Bands with the exact same first row by Mike Shenk published in the Wall Street Journal. The resemblance ends there, but I found the duplication amusing. Both puzzles have their good points, but I happen to prefer my continuation of the second entry in Band A. I doubt Shenk had seen my puzzle, but if I had seen his first, I wouldn't have written this one. I don't like to use someone else's wordplay in the same sort of variety grid puzzle, though I am willing to use, say, an entry in someone else's Spiral as a bottom-row entry in a Marching Bands.
