A few years ago, Robert Plant thought he was done making records. But the former lead singer of Led Zeppelin discovered he still had at least one more left in him. His new album, “Saving Grace,” is named after the band he’s been performing with for the last six years. It’s a collection of 10 musical interpretations and covers of songs by a variety of artists. Robert joins Tom Power to talk about finding new inspiration in old music, why he's not precious about the past — including his time in Led Zeppelin — and this great quote he has about Bob Dylan: “Dylan didn’t tap me on the shoulder, he hit me between the eyes.”
