Sheryl Crow is set to tour American college campuses to raise awareness about global warming.
The singer will travel from town to town via a bio diesel bus visiting 11 universities. She'll be joined on the tour by environmental activist Laurie David. Sheryl said, "I am here because the more I learn about global warming, the more I feel compelled to do something in my own way, whatever that is." The tour will comprise some of Sheryl's best-known hits along with presentations and video clips on global warming. |
