“The day we wrote this song, I actually said, ‘Man, I think John Mayer can really do something special with this song by playing the solo,” Wilson says. “From my mouth to God’s ears, the day we were recording the song in L.A. at Chaplin Studios — John actually owns the studio now — he was there, and we went into his studio and played him a little bit of what we had been working on, and he said, ‘I’m in. Let’s go. Let’s do it right now.’ He literally picked up his guitar. He played acoustic on it real quick, and the next thing you know, he was shredding on his electric guitar. It was a very organic situation. It wasn’t even a plan. Sometimes, I think that’s when things are even more special and come out better than you imagine when they are just spur of the moment.”
