It marks the first time Elvis Costello has ever played lead guitar on someone else’s song. It was recorded in just a few takes in the winter of 2008, and is considered to be the first Jenny and Johnny song.
Interestingly, this same song was a Japanese bonus track on Jenny Lewis's last solo album, "Acid Tongue". It's not clear if it's the same version or not.
