Former Grateful Dead guitarist Bob Weir and his band RatDog canceled all their performances through 2015.Bob Weir and RatDog are one of the great jam bands but even jam bands get tired. Bob Weir won't be on the road this year with RatDog.

The Lockn' Festival, one of the show affected by Bob Weir's cancellatins announced they will replace Weir with Bill Kreutzmann's Locknstep Allstars. Grateful Dead drummer Bill Kreutzmann will lead the performance. The "Allstars" will be revealed over the next few days. Funk revivalists Lettuce have also been added to the lineup.

Lockn' co-founder Peter Shapiro explained on the Relix.com website "When we found out that Bob Weir wouldn't be able to make it this year, we decided to keep it all in the family by asking his brother Bill to join us at Lockn'. We are all looking forward to the premiere of Bill Kreutzmann and the Locknstep Allstars. For those of you who are curious just what Locknstep is, join us in September and we'll all find out together." According to the Lockn' website, organizers "have been working diligently to make schedule adjustments that honor the integrity of their vision for Lockn' and all of you who have purchased a ticket and invested in Lockn'."

Former Grateful Dead guitarist Bob Weir's team announced that will cancel all remaining tour dates including the Jamaica event scheduled for January, 2015. Full refunds will be offered.

Bob Weir and RatDog posted the announcement to their Facebook page:

"Circumstances have necessitated that all scheduled tour dates for Bob Weir & RatDog are being cancelled. This applies to all dates on the summer tour starting on Thursday, August 14 in Boston through September 14 in Nashville and also includes the Jamaica event in January of 2015. Full and complete refunds are available at place of purchase. We sincerely apologize for any inconvenience.
