David Cook & Jennifer Hudson at Walmart Shareholders Meeting

Apparently the winner of AI has to perform at an Annual Wal-Mart Shareholders meeting. David Cook sang "The World I Know" and "Time of My Life" while accompanying himself on acoustic guitar and shared some of his Wal-Mart memories. (No "Do they sell walls there?" joke).

Jennifer Hudson performed "I Am Telling You" and "Spotlight."
