In an effort to help the more than one million young people in the United States who experience homelessness every year, the cast of FOX's hit musical special Grease: Live partnered with DoSomething.org for its annual Teens for Jeans campaign, encouraging youth to collect jeans for the homeless. FOX promoted the campaign across its social media platforms during the live broadcast on Sunday, January 31, and members of both the cast and the audience got involved, as well.
