Crazy to think that at one time people freaked out over this sort of "rock and roll" music! Also: where did these kind of night clubs go? Might be for going to "the club" if they were a LOT more like this (no offense to the "clubs of now" at all, though.) Super old fashioned, I know, but that's just me. : )
Late July 1955 we were hearing a ton of the HOT new song by Bill Haley & His Comets - 'Rock Around The Clock' -- for you younger boomers, hard to begin to explain how big a deal this song was when it hit.
Here's a cartoon cover of Bill Haley and The Comets. They were among the prominent Rock n' Roll groups during the 1950s. Albums were among the new goods that teenagers were able to buy.

James Dean in Omnibus -episode "Glory in the Flower" aired in 1953, where he danced to the song "Crazy Man, Crazy" by Bill Haley and his Comets. This was one of the first dramatic TV programs to ever feature rock and roll.
