Answer:
The original and cover songs share the same lyrics, but have different beats adding up to different feels.
Step-by-step explanation:
Big Joe Turner has a lot more elements of the blues and Bill Haley has a more rock and roll approach, Rock and roll has its origins on rhythm and blues, and became more commonly used by white performers. Junior Parker also has a lot of elements from the blues and soul rhythms, while Elvis Presley makes a mix of rock and roll and country. The original songs have a deeper, more emotional twist in their vocal interpretation, as for the covers, they have a more technical approach.
The cover versions are a "rip-off" of the originals, because of the social context. It is a form of cultural appropriation, leading to the cover artists becoming more popular and often treated as the original creators of the songs and genre. The original versions have a better feel since the songs were written and recorded to their specific social context, deeply communicating the author's feelings.
