Gaga in Rockefeller Plaza

GAGA FOR GAGA: A record crowd of more than 20,000, some of whom waited up to 33 hours, gathered in the pouring rain at N.Y.’s Rockefeller Plaza this morning to see a free performance by Lady Gaga for The Today Show. “Let it rain. Let it pour. You can’t stop us,” she proclaimed before her last song, “Teeth.” The 24-year-old mega-star opened the set with Gershwin’s “Someone to Watch Over Me” and sang a new song, “You and I,” as she descended from a fog-shrouded platform onto the white and electric blue stage.
