• This is one of three new songs on R.E.M.'s compilation album, Part Lies, Part Heart, Part Truth, Part Garbage 1982–2011, which was released after the band announced they were disbanding. Bassist Mike Mills told Billboard magazine that whilst the other tracks were written with the break up in mind, he wasn't sure if this one was, "but it applies in a really cool way. First of all, lyrically, like, 'hey we don't work at the same job any more.'"
• The title is a play on the Southern expression "A month of Sundays," which means a very long time. R.E.M.'s hit "Losing My Religion" is also titled after a Southern phrase.
• Mills told Billboard magazine that the three new songs on the album show the three sides of R.E.M. over the years with this one demonstrating the "playful goofy side." Said Mills, "Then there's the harder-edged 6/4 time 'Hallelujah' that we write. And then there's the soft, wistful midtempo ballad that we do . It's three facets of R.E.M. in 2011 that are extremely well represented."
• "I was thinking Pylon when I wrote it," Mills wrote in the liner notes for the compilation, "so it's my tribute to Randy Bewley." Pylon is a fellow alt rock band from Athens, Georgia, with Bewley on guitar.
