Unreleased Dylan Single to be released April 20th

Dylan fans: here is one reason to get to a local record store on April 20th...  I may have to get it for the cover alone.

From Bob Dylan's website:

"Wigwam single to be released for Record Store Day

In celebration of Record Store Day 2013, Columbia Records will release a 7" vinyl single featuring an unreleased demo of "Wigwam" backed with a previously unreleased recording of "Thirsty Boots" from the forthcoming Bootleg Series Vol. 10.
Pick up your copy on Saturday, April 20, at participating independent record stores."
