Calexico's Joey Burns took his ukulele to the WFUV Christmas Concert in 2013 and got Beth Orton, Sam Beam (Iron & Wine), Glen Hasnard (The Frames/Swell Season), Nick Lowe, Kathleen Edwards, Amos Lee and everyone in his band to sign the instrument. Then, while performing on Conan, Burns had Neko Case, Jon Rauhouse, Kelly Hogan and Eric Bachman make their mark on the ukulele as well.

Now Burns is auctioning off the signed ukulele as a fundraiser for Tucson's community radio station KXCI. The instrument itself is a Carlo Robelli soprano ukulele with a sapele body, nato neck, rosewood fingerboard and bridge and chrome tuners.

The auction ends on Wednesday, June 17, and with two days left, the auction is only up to $136 (at the time of this post). You can put your bid in by visiting the item's Bidding for Good page. The winner can either pick up the uke at KXCI headquarters (220 S. Fourth Ave.) or opt to pay for shipping.
