Sheryl Crow has teamed up with environmentalist Laurie David (wife of comedian Larry David) for a tour of various US college campuses to discuss the growing problem of global warming. Traveling on a bio-diesel bus, the singer is acoustically performing songs such as ” “Everyday Is a Winding Road” and “Soak Up the Sun” with guitarist Tim Smith at each one of the shows. In addition, a documentary crew is following Crow & David through the tenure of the entire show, to hopefully create a DVD in the end similar to that of Al Gore’s An Inconvenient Truth.

The Stop Global Warming College Tour wraps on Earth Day (April 22) in Washington, D.C.http://www.billboard.com/bbcom/news/article_display.jsp?vnu_content_id=1003571637
