Yeah, but you SURVIVED!
So one thing you can take from this is inspiration!
Stuff goes wrong sometimes. Horribly, horribly wrong.
For us, it usually happens somewhere we were really trying to impress the owner, because it was a fantastic venue for us.
My favorite is when my wife was playing bass, and the guitar player was tuned in a different key, and they started playing "Fire," by Jimi Hendrix, in TWO DIFFERENT KEYS.
I tried to sing, but I didn't know who to sing to, so I'm pretty sure I was switching back and forth between the two keys, and sometimes landing somewhere in the middle.
I stopped the song, and my whole band yelled at me.
"YOU NEVER EVER EVER EVER STOP A SONG!!!!!"
Actually, there is one time you stop a song.
That's when the bass and the guitar are tuned to two different pitches, and you are the lead singer.
THAT is one time you ALWAYS stop the song, even if you're playing freaking on a WORLD WIDE SATELLITE HOOKUP TO THIRTY MILLION PEOPLE.
Because it would be UTTERLY IMPOSSIBLE to make that sound good.
It simply can't be done.
Anyway, we did play there again; in fact, the rest of that night went fantastic, and the audience loved us, we got paid, the whole deal.
But while it was happening, I thought we looked like the worst, most amateurish band I had ever run across.
No one died.
Similar thing happened to me.
Our band was opening the second set with I Want You Back by the Jackson 5. Two measures in and we had to stop. Something was very awry with the sound.
Not one, but both guitarists forgot to put their capos on and were playing in a different key from me.
