My Morning Jacket singer Jim James sat in with these traditional New Orleans old-time jazz legends for a song on a benefit effort to support the group. First recorded by early jazz great Fats Waller, this version hews closer to that than anything written by MMJ. For authenticity, it was recorded at Preservation Hall's hallowed French Quarter home base, where fans can see the band nightly. "What a thrill," recalls James. "We did it old-school: all live with no electricity, and the garbage trucks even played along!"
