The dancers consist of two men and two women dressed in 1950s fashion. They have an orange outline.
P1 is a man with short black hair. He wears an orange suit with black accents and lavender cuffs hidden in his sleeves, a light orange button shirt with a black string tie, orange pants secured by a red belt and black shoes with white accents on the top.
P2 is a woman with a high volume black hair, with parts of her hair resting on her shoulders. She wears a red and white sleeveless checkered top with the bottom part tied up, a long red skirt secured by a black belt and black strap-on heeled wedges.
P3 is a man with black hair styled in a pompadour. He wears a dark orange T-shirt with a black sleeveless greaser jacket over it, black jeans secured by a black belt and black shoes.
P4 is a woman with black hair in a short beehive with messy bangs. She wears a pink and red bustier with red sleeves, pink high waist pants with black buttons, pink socks and black doll heels.
The first dancer has black hair, a red cowgirl hat, an aqua glove, a red skirt, an orange top, and black boots. The second dancer has short black hair, a brown cowboy hat, an orange cowboy shirt, a yellow glove, a brown belt, black trousers, and brown boots. The third dancer has black hair, an orange cowgirl hat, a light blue glove, a short brown top, an orange belt, brown trousers, and black boots. Only the second dancer is playable.
The background looks like a jukebox with vinyl records inserted. In the background, an old-style microphone can be seen. The platform on which the dancers are dancing on seems to be a huge record with flashing lights by the borders.
There is 1 Gold Move in this routine:
Gold Move: This is a wave Gold Move that starts from P4 and ends with P1.
P4: Cross your hands out in front of you, then place them on your head.
P3: Pretend to comb your hair with your right hand.
P2: Put your hands up near your head one by one, and shake them slightly.
P1: Move your arms in a circle in front of your face.

Gold Move in-game
There are 2 Gold Moves in the Line Dance, both of which are the same. They are only available on Just Dance Unlimited and Now.
Both Gold Moves: Lift up your right leg and open your arms to the left.
However, Jailhouse Rock is the only song of the three to not originally be from The Blues Brothers.
Jailhouse Rock was the first song to have a Line Dance routine in the series.
Jailhouse Rock is tied with Wild Wild West as the Dance Crews with the shortest pictograms sprites in Just Dance Now (22).
If the whole franchise is taken into account, they are beaten by Waterloo’s remake (21).
The coaches were likely going to have different color palettes, as the Just Dance Now files contain a pictogram that is indigo, orange-brownish, dark gray and ochre yellow instead of orange-brownish, red, black and ancient pink.
The Gold Move pictogram looks like a Just Dance 4 Gold Move pictogram, hinting that the routine was intended to have Gold Moves since Just Dance 4.
The Line Dance is not available in the Wii version of Just Dance 4.
This makes Jailhouse Rock (Line Dance) the first alternate routine to not be available on the Wii.
Jailhouse Rock (Line Dance Version) was the first alternate routine to be added to Just Dance Unlimited and Just Dance Now.
Jailhouse Rock (Line Dance Version) and Starships (Charleston Version) are the only alternate routines in Just Dance Now to have their respective alternate themes listed instead of simply being labeled as "ALTERNATE".
As is the case with Oh No!, the Line Dance features a trio while only the lead dancer is playable.
The background dancers, however, have gloves as well.
All the coaches are affected by a chroma key glitch that makes some parts of their gloves turn orange.
There are several differences between the Just Dance 4 and Just Dance Unlimited/Just Dance Now versions of the menu icon for the Line Dance:
In Just Dance 4, the neon lines are pink, the background is smokey and purple, and vinyls are shown at the bottom right corner; in Just Dance Unlimited/Just Dance Now, instead, the neon lines are greenish, the background is less blurry and speakers are shown instead of vinyls.
The dancers’ faces are less visible in Just Dance 4.
In Just Dance 4, the left backup dancer is slightly closer to the screen; in Just Dance Unlimited/Now, instead, they are at the same distance.
In Just Dance Unlimited, the backup dancers in the album coach are semi-transparent.
This was fixed in an update, where both of them are in full opacity.
In addition, the outlines are thicker and separated (each dancer has his or her own), the color schemes are brighter and the coaches’ facial features are much less visible.
Jailhouse Rock (Line Dance) was erroneously listed in the Trios playlist in Just Dance Now for a short period.
