Joe Bonamassa's intro riff on this BCC tune really grabbed me, so between listening carefully and watching him play it on this YouTube clip, I think this is pretty accurate:

It's really not very difficult at all. You JB fans (yeah, Rev, I'm talkin' to you!), give it a try and let me know what you think.
