Here's one:
1989 Blue Devils Solo
Imagine this -- you're the soprano soloist for the multiple time World Champion Drum and Bugle Corps. It's finals night and you're performing in front of 30-40,000 people, most of whom have marched corps. You have an upper register solo, in the ballad, on G Bugle. You've nailed it every night in the whole season, but tonight, when it really counts, something goes wrong.
It's a true story. The soloist is now a lawyer in CA.
