Did any of you see any of the eddie and the cruisers movies

The very first rock song ever was y Bill haley and the comets. It was used as the theme song for happy days. After that it came elvis with that's alright momma. Berry came later. He is the acknowledged king of rock and roll. Blue swayed shoes, hound dog, and so many others are classics.

This is total BS. Chuck Berry was writing rock and roll songs in the late 40's....if by came before you mean Elvis was famous before Berry that would be correct.

But you might want to keep in mind that Elvis not only didn't write the music, he also didn't write the lyrics.....Chuck Berry did both....and he was the inventor and king of rock and roll....
