Started a song in church this morning in "G." Except it was supposed to be in "D," and after the first few notes it became painfully obvious that it was way too high to sing. So I had to stop everyone and start over in the correct key, which was way better than trying to continue in the wrong key. (Which I have also tried, hoping no one would notice, with poor results.) Hey, stuff happens; just correct it and move on, nobody is going to remember the occasional mistakes. That's my story and I'm stickin' with it.
