It happens. And when it happens, the show must go on...
It would have been easy for this Band, Great White, to cancel the show, just like it would have been easy for them to quit the music business entirely after pyrotechnics they used during a show in at The Station in Rhode Island started a fire and killed 100 people, including the band's guitarist, Ty Longley.
But they didn't.
Say what you will about Great White, but they're not quitters. And that's more than can be said for most musicians.
