Buddy Guy and John Mayer perform "What Kind of Woman Is This?" live at Farm Aid 2005 at the First Midwest Bank Amphitheater in Tinley Park, Illinois on September 18, 2005.
Farm Aid was started by Willie Nelson, Neil Young and John Mellencamp in 1985 to keep family farmers on the land and has worked since then to make sure everyone has access to good food from family farmers. Dave Matthews joined Farm Aid's board of directors in 2001.

Farm Aid's performances are donated by the artists in order to raise funds and raise awareness for family farmers. They've raised their voices to help — what can you do?
