Watch: Redskins' Nico Marley performs grandfather's song at karaoke

Washington Redskins rookie linebacker Nico Marley may not have inherited the singing ability of his grandfather, Bob Marley, but he does know how to command a stage.

Marley performed a rendition of his grandfather's song "Waiting in Vain" while at a karaoke-inspired fundraiser Friday for Mobile Hope, a Virginia non-profit organization that assists homeless and at-risk youth, according to CSN Mid-Atlantic's Brendan Darr.
