Amy Helm on music, family and her father’s legacy

Singer-songwriter Amy Helm is the daughter of legendary drummer Levon Helm. She grew up in Woodstock, New York, with a front-row seat to music history. Long a collaborator, she’s broken out on her own in recent years with her third solo album, “What the Flood Leaves Behind,” released last month. “CBS This Morning” co-host Anthony Mason spoke to Helm.
