As per the title - do any of you fine people know where this vamp is from. Or what it sounds like? (Possibly multiple songs.)
(This is just a 2-bar mock up.)
Sounds like a high energy 1970s southern rock type song, or maybe something more recent, like the Georgia Sattellites.
But different … so if it’s yours, run with it!
I think I will! If I can ever compose the other 100+ bars!
That’s more like it - what’s it called?
LaGrange ZZ Top!
But check out this John Lee Hooker tune too (speed it up about 15%)
This is great, thanks. I knew I’d heard it somewhere, but I can see it’s quite the staple of up-tempo blues.
Which means I can safely rip off everyone! Whoo hoo!
It’s that dang Authentic Iintelligence! Artists been using it to steal from humans for millennia
My 2 cents: I think it’s safe to say that you are not at risk to run into copyright issues. This is a common pattern which has been used a lot. Make it your own by throwing loads of cowbells at it 
I will do my best, sir!
from a legal standpoint, a single cowbell should do the trick*
