Well, new to me. And it was slap my forehead "Why didn't I figure that out sooner thing" also.
But it these little gems that I find the most enjoyable part of guitar playing. Learning a practicing something NEW until I've got it down.
I was watching the Aerosmith special on A&E and saw Perry play "Baby Please don't go". I've liked that tune for decades, but never learned to play it. Ok, it's pretty easy, but I'm not that good either. Plus carpul tunnel in my hands has robbed me of alot of my former ability. But still, I enjoyed learning it.
