Paul McCartney welcomed Jack White and St. Vincent to play on the guitar duel on "The End" during his set at Mexico City’s Corona Capital festival Sunday night. Watch it on YouTube.
St. Vincent also played lead guitar on "Get Back." McCartney now takes his Got Back tour to Europe starting December 4th for two shows in Paris followed by two in Madrid, and four in England -- two in Manchester and two in London where it ends on December 19th.
