Singer-songwriter Bob Dylan has a birthday today. The man who wrote Forever Young is now 60 years old. His influence on popular culture is strong. He also influenced many to pick up the guitar and sing. Dylan's music inspired a fellow Minnesotan named Bob Feldman to start a record label dedicated to recording great singer-songwriters. Red House Records has just released A Nod to Bob, a collection of artists interpreting their favorite Dylan songs. We hear from four of the artists. Guy Davis sings Sweetheart Like You, Eliza Gilkyson does Love Minus Zero, No Limit, Lucy Kaplansky sings It Ain't Me Babe, and Martin Simpson performs Boots of Spanish Leather.
