VIDEO : John Legend and Juanes Sing in Arizona to Bring Attention to Detained Immigrants

On Wednesday, before a small crowd, Juanes and singer John Legend met immigrants at a jail in Arizona before performing outside the facility to draw attention to immigration and mass incarceration.

The Grammy winners each played two songs separately and one together ? Bob Marley's "Redemption Song" ? as dozens of people sang along in Eloy, about 60 miles southeast of Phoenix.
