I need to find an easy blues song, preferably in A for a end of year show for guitar students. I just can't think of something. It has to be something that people can recognize.

Just like a 12 bar blues, and if it isn't in A, I can transpose it.
I'm a tone wh0re and a gear slut.
You should just make one up. It's extremely easy. There's like a freaking formula for it. Why do you want it to be in A?
I have too much gear to fit!
just get th a blues scale at your fingertips
get a mate to play the blues progression
and wank off your guitar
easy peasy
Yeah, I know making one would be easy, but its for someone to sing over it, and in A cause its the easiest way. Some students are really young.
