^^^^ Its on ratdog.org which is ratdogs web site, I think that makes the Beacon official. All shows have been a bit dicey for the beacon this year becasue it was allready suppose to be closed down for rennovations. Thats maybe why its not listed anywhere else yet.
MSG is now listing "Bob Weir and Ratdog" on their Beacon Theatre line-up for the dates listed above. So, it looks like they are official official now!
