Some celebs lend their name or give a bit of time or money to a cause, but Travis McCoy is willing to travel the globe. As the ambassador of the Staying Alive Foundation (MTV’s global AIDS charity), the Gym Class Heroes front man traveled from South Africa to the Philippines to India to encourage and empower young people who are involved in HIV/AIDS awareness, education and prevention campaigns. In addition to his work on the ground, he also wrote a song about it. If you want to help Travis save lives, then download “One At A Time” at www.stayingalivefoundation.org. All proceeds will fund global HIV prevention projects.
