This show was postponed due to strain on Dave's vocal chords, then later canceled.
From Dave's Twitter:
"I'm very sorry for cancelling the show. I guess a snow day is better than early retirement. I just hate cancelling shows. Broken contract."
"The fact that the cancellation happened in salt lake again is even more frustrating. Im truly sorry. If you see me in the grocery store...."
"Flip me the bird."
