Frontman Tim Burgess told NME the story of this song: "We wanted to make a track that sounded like the summer, because we were freezing," he said. "That was a very us thing to do – try and make something that takes us out of this world that we're in right now and transports us to a new place. We came up with 'So Oh,' about travel and love and sunshine, and it felt good to make that track."
Mike Campbell from Tom Petty & the Heartbreakers played the slide guitar on "Sixth Avenue Heartache." There is a connection here - Wallflowers lead singer Jakob's dad, Bob Dylan, played with Tom Petty in The Traveling Wilburys.
