Take a listen to this John Lee Hooker song and you tell me if you think it's a direct rip off (rather than a coincidence).
Did you think of this straight away?
John Lee Hooker recorded that song in 1962,
Daniel Flores who used the stage name 'Chuck Rio' wrote Tequila and recorded with the Champs way back in 1958.....
(I gotta say it hurts to think Bo Diddly borrowed the rhythm structure)
