WOW!
I am shocked at this...if the real reason is lagging sales or the schedule that is catching up with them, these shows could have been cancelled weeks ago. It must be bad for them to cancel shows the day of, whatever the reason.
I keep thinking of Stevie's famous Rolling Stone interview back in the 70's when she said "you cannot call in sick to Fleetwood Mac".
I am sorry for the No Cal FM fans too...
