A host of musicians — including R.E.M.’s Peter Buck and Mike Mills, as well as Alejandro Escovedo, members of Sleater-Kinney, The Decemberists, Drive-By Truckers and The Shins, and more — will perform two concerts in Portland, Ore., next month to raise money for Scott McCaughey, who suffered a stroke last month.

In this clip recorded for Levi’s ‘Pioneer Sessions,’ James Mercer — leader of The Shins and one-half of Broken Bells — throws down a solo-acoustic cover of Squeeze’s classic ‘Goodbye Girl,’ which also is available as a free download.
