Margaritaville.com has posted an announcement on the October 2009 tour dates that were originally announced back in February:
It has come to our attention that some fans have been disappointed to find that the shows tentatively scheduled for October are no longer going to happen due to unanticipated scheduling conflicts. We’re sorry for any inconvenience this may have caused you and look forward to seeing you back in Las Vegas and on the West Coast in 2010!
