Wal-Mart faces pressure at annual meeting, but it doesn't spoil the party

Wal-Mart hosted its annual shareholder meeting Friday morning, a confab more like a star-studded corporate pep rally than an investor event. Pharrell Williams started the meeting by singing "Happy" at 7 a.m. central time in front of a video of company employees dancing to the popular hit song. Robin Thicke, Sarah McLachlan and Florida Georgia Line also entertained. Chief executive Doug McMillon took a selfie with four of the thousands of Wal-Mart workers flown in from 27 countries.
