The dancers are wearing 50s fashion attire. They all have a orange outline.
P1 is a man with short black hair; he wears an orange suit with a pair of matching orange trousers, and a pair of black shoes.
P2 is a woman with long black hair; she wears a red-and-white spotted top, a red skirt, and a pair of black high heels.
P3 is a man with black hair styled in a similar way to Elvis Presley's; he wears a reddish-orange shirt, a small black leather jacket, a pair of black trousers, and a pair of black shoes.
P4 is a woman with black hair; she wears a red-sleeved shirt, a pair of pink trousers, and a matching pink bra.
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.
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.
The Line Dance is not available on the Wii version of Just Dance 4.
This is the first alternate routine to not be available on the Wii. It is followed by Blame It on the Boogie (Extreme).
With the exception of Just Dance 4’s Mashups, the Line Dance is the first post-Just Dance routine to not have any Gold Moves. It is followed by Blurred Lines (Fanmade).
The coaches were likely going to have different color palettes, as the Just Dance Now files contain a pictogram that is Downriver/Tabasco/Mine Shaft/Buttered Rum instead of Tabasco/Totem Pole/Cod Gray/Siletto.
This song was the first to have a Line Dance routine in the series. It is followed by Hit The Road Jack.
All four coaches from the Classic routine make an appearance in the background for You’re The One That I Want as black silhouettes.
The Gold Move pictogram for the Line Dance looks like a Just Dance 4 Gold Move pictogram. Therefore, the Gold Move might have been intended to be in that game as well.
Jailhouse Rock (Line Dance) was erroneously listed in the Trios playlist in Just Dance Now for a short period.
In addition, Jailhouse Rock (Line Dance) 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 "ALTERNATE".
All the coaches in the Line Dance are affected by a chroma key glitch that makes some parts of their gloves turn orange.
On Just Dance Unlimited, the backup dancers in the album coach for the Line Dance are semi-transparent.
The Classic album coach for Just Dance 4 is different from the one seen in Just Dance Unlimited: while the former has a red, pixelated outline, the latter has a pink, faded one.
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 (21).
There are several differences between the Just Dance 4 and Just Dance Unlimited/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/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.
