According to John Mellencamp, "Jack & Diane" was based on the 1962 Tennessee Williams film Sweet Bird of Youth.[8] He said of recording the song: "'Jack & Diane' was a terrible record to make. When I play it on guitar by myself, it sounds great; but I could never get the band to play along with me. That's why the arrangement's so weird. Stopping and starting, it's not very musical." Mellencamp has also stated that the clapping was used only to help keep time and was supposed to be removed in the final mix. However, he left the clapping in once he realized the song would not work without it.
In 2014, Mellencamp revealed that the song was originally about an interracial couple, where Jack was African American and not a football star, but the record company persuaded him to change it.[9]
In 1982, producer and guitarist Mick Ronson worked with Mellencamp on his American Fool album, and in particular on "Jack & Diane." In a 2008 interview with Classic Rock magazine, Mellencamp recalled:
Mick was very instrumental in helping me arrange that song, as I'd thrown it on the junk heap. Ronson came down and played on three or four tracks and worked on the American Fool record for four or five weeks. All of a sudden, for "Jack & Diane", Mick said, 'Johnny, you should put baby rattles on there.' I thought, 'What the f*ck does put baby rattles on the record mean?' So he put the percussion on there and then he sang the part 'let it rock, let it roll' as a choir-ish-type thing, which had never occurred to me. And that is the part everybody remembers on the song. It was Ronson's idea.[10]
Cash Box said that "this shuffling pop 'ditty'...has a certain power that hits to the heartland with a warm, descriptive storyline that’s both personal and universal."[11]Billboard said that "The hooks here are in the storyline, which traces a blue collar romance 'in the heartland' where Cougar hails from, capped by taut guitar and percussion."[12]
The 1982 music video featured Mellencamp and his then-wife, Victoria Granucci. [13]
