Robert Plant and Alison Krauss dipped into the Led Zeppelin catalog at their tour opener Wednesday night in Canandaigua, New York.
It was their first full show together since 2009 and besides tracks from their two albums of material, they did three songs from Led Zeppelin IV -- “The Battle of Evermore," "When The Levee Breaks" and -- for the first time ever -- "Rock and Roll."
Watch the "Rock and Roll" performance on YouTube.
