Born in York, Pennsylvania, but reared in North Carolina and Virginia, the country singer Robbie Fulks came to New York in 1980, to get off the farm (his parents were back-to-the-landers) and enroll at Columbia: “I didn’t know that there wouldn’t be women there, or even that it was in the Ivy League,” he said the other day. He dropped out after two years to give the singer-songwriter thing a go.
