Exactly. Many youngsters I meet today who were inspired by more contemporary guitarist usually don't realise that their heroes were in turn influenced by Chuck. He was definitely one of the 'founding fathers' of modern guitar playing.
I thought the parent was referring to playing a fifth on the top two strings with a slide, not the blues shuffle (which dates back to at least Robert Johnson).
Cyberferret refers to "the opening riff to Johnny B Goode", which is extremely similar to the opening riff from Ain't That Just Like a Woman. For some reason the link I pasted started several seconds in, which might be causing confusion.
Thanks for posting, and for fixing the link too - I played it the first time and missed it, and thought that you were talking about the standard blues shuffle beat too.
