And most who associate that riff with Chuck Berry aren't aware of this 1946 version of it:

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.

Ah I hear it now! Somehow I missed that on the first listen and was very confused.
