How to sort a list in Scala by two fields?

how to sort a list in Scala by two fields, in this example I will sort by lastName and firstName?
case class Row(var firstName: String, var lastName: String, var city: String)
var rows = List(new Row("Oscar", "Wilde", "London"),
new Row("Otto", "Swift", "Berlin"),
new Row("Carl", "Swift", "Paris"),
new Row("Hans", "Swift", "Dublin"),
new Row("Hugo", "Swift", "Sligo"))
rows.sortBy(_.lastName)
I try things like this
rows.sortBy(_.lastName + _.firstName)
but it doesn't work. So I be curious for a good and easy solution.
Thanks in advance!
