Jerry Flowers and Tony Martin started the song off, before bringing in Wendell Mobley later. It took them a year to complete it to their satisfaction. Martin recalled to The Boot
"Jerry and I spent a whole day [on it]. And I think eventually he had to go on the road with Keith [Urban] or whatever. And I had just said the line, "A little more summertime - I had a little more summertime."
And even though it never was kind of anything, it sat around, probably even before I brought it up to Wendell one day. We couldn't come up with anything. I said, "I just remember this thing with Jerry: 'If I had a little more summertime.'"
Wendell Mobley continued: "[Flowers and Martin] had it kind of started already, and then we worked on it a little bit. By the time it was over, we worked on it - I can remember working on it one May, and then the next May getting it out again. It was old-school writing. It's like, "Hey, what about that idea we were working on?" We just kept working on it and working on it.
"I promise you, there are more parts to this song that didn't make it in the song than [there are parts that] actually made it. What we started with, we didn't use. The only thing that made it through actually was the title. We were still cutting stuff off when we were demoing it."
