"Livin' on a Prayer" is Bon Jovi's second chart-topping single from their 12× platinum Slippery When Wet album. Written by Jon Bon Jovi, Richie Sambora, and Desmond Child, the single, released in late 1986, was well received at both rock and pop radio and its music video was given heavy rotation at MTV, giving the band their first No. 1 on the Billboard Mainstream Rock chart and their second consecutive No. 1 Billboard Hot 100 hit.
The song has become the band's signature song, topping fan-voted lists and re-charting around the world decades after its release. The original 45-RPM single release sold 800,000 copies in the United States, and in 2013 was certified Triple Platinum for over 3 million digital downloads.
The song is about a fictional working class couple, Tommy and Gina, who struggle to make ends meet and maintain their relationship. Tommy "used to work on the docks" because "union's been on strike, he's down on his luck". Gina works at a diner, "workin' for her man".
The video for the song features shots of the band rehearsing, then playing in front of a crowd. The first half of the video, featuring the rehearsal footage, is black and white, and the second half of the video, performing to the arena audience, is in color.
