Rick Springfield was scheduled to play the Fallon County Fair in Montana on August 16, but his gear was damaged by a storm and he was not able to perform.
At least (apparently) no one was hurt:
(Facebook post embedded above, if that doesn't work try this link).
Oh and there were no reports of tornadoes yesterday in Montana on the 16th, but this certainly was a strong storm, and the SPC shows a report of a wedding tent blown down, also in Fallon, MT (blue dot up by Montana/ND/SD border).
There have been so many of these events that I have a whole category of posts here.
