(CMT Offstage keeps a 24/7 watch on everything that's happening with country music artists behind the scenes and out of the spotlight.)
What I'm gathering from this Twitter exchange between Brad Paisley and Jewel is that he was doing some de-cluttering around his house over the holidays and Jewel just wanted to see what he'd found. Paisley tweeted first, "100 yrs ago my great grandma traded a cow for this. 1st guitar in our family. Ran across it today. Happy new year." It had a picture of an old guitar case that said "The Mountain Kid" on it. Jewel replied to his tweet with "Let's c inside the case!" And so he got back to her (and the rest of the country-loving world) with a picture of the actual guitar inside.
