If all unicorns were this inconsiderate and careless, it's no surprise that they didn't last. Realistically, I can't imagine that a "one-anything band" has survival in its future. When was the last time you saw a one-man band? Aside from Bert in Mary Poppins, I've never seen one. I assume they were killed off before I was born by tigers, multi-man bands, and natural selection. The traditional one-man band is most likely extinct because it only performed one song... and that song had no title, no melody, and was as soothing on the ears as a train wreck. A solo bander doesn't make music... it makes noise.
My feelings about "noise" make me realize how old I'm getting. When I was a kid, adults were always telling me to quiet down. I couldn't figure out why old people were so objected to sound, but somewhere in the last thirty years... I got old. Last week someone cruised by our house on a motorcycle, and I thought, "What, are you trying to wake up the whole neighborhood?" I was also upset that the motorcyclist was visiting our street from a world without speed limits. What? I'm way too young to be this old. Fortunately I didn't confront him or I'd have probably ended up offering him sixpence to get a haircut. Crazy hooligan!
Wait, was this about unicorns? They were hooligans too.
