Here's another little shuffle I like to warm up with. It took me a little more time to get it down (your mileage may vary), but once I did, I found it's fun to play.
Again, echo helps give it more of a rockabilly than a blues feel, though you might even be able to coax a little country feel from it.
The turn around is a Buddy Holly style turn around, which I haven't quite got right using the MIDI, so dig out your Buddy Holly records and you'll find the right rhythm.
