Each installment of An Evening With presents a performer, band, group, or other public figure in a setting aimed to please fans looking for a representative sampling of what a particular person or group of people does best. In this video, actor and comedian Robin Williams returns to his stand-up roots. Mainly relying on improvisation and sheer manic will, Williams performs before an appreciative audience at the Great American Music Hall in San Francisco. ~ Rob Ferrier, Rovi
