It is worth noting that back then songwriter and performer were basically separate jobs, and it was very common for multiple artists to record the same song, sometimes even at the same time and competing on the charts. Hound Dog is written by Lieber and Stoller, the legendary songwriting duo, and recorded by multiple artists, including Thorpe and Elvis. The performer only got paid for their own performance, but the songwriters got paid for every recording (depending on the contract).

All this changed with Beatles and Bob Dylan, because they made it the expectation that "real artists" wrote their own material. This caused the idea of the "original version", and consequently the "cover version" which was a recording by any other artist than the original writer/artist.

So not to dispute that Rock n Roll was originally black music which made a lot of white artists rich and famous, it is still interesting to note how many of the songwriters at the time were Jewish. Just another aspect of the story!
