Vassar Clements on fiddle, Mark O'Connor on mandolin, Béla Fleck on banjo, Jerry Douglas on dobro, Junior Huskey on bass. Who’d they get together for?

Jimmy Martin and The Nitty Gritty Dirt Band, that’s who. As you might expect, everybody has a blast and brings it, too. It’s hard to pick a favorite when they’re all “"Sittin’ On Top Of the World”.
