"Summer of Love" originally aired as part of "American Experience" in 2007, but what better time to repeat the documentary than during this Summer of Mistrust? The film focuses on the youth migration to San Francisco's Haight-Ashbury.

Talking the talk

David Letterman has said Norm Macdonald is one of the funniest people he knows (Al Franken is another), which may explain why the former late-night host is making an appearance on the fairly low-profile project "Norm Macdonald Live." The two are clearly big fans of each other in this engaging, relaxed conversation about everything from being sabotaged on "The $20,000 Pyramid" to working with Mary Tyler Moore on her ill-fated variety show. A must-see for comedy fans.
