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.
