Two weeks ago Samuel L. Jackson took to social media to challenge celebrities to speak out against police brutality by singing "We Ain't Gonna Stop, Till People Are Free."
Take a look at Jackson's video:
R&B singer Luke James took Jackson up on his challenge and did a soulful rendition of the song.
Not to be outdone, members of Baltimore's Dru Hill showed that they still have their harmonizing abilities.
Although Jackson's challenge hasn't been done by as many celebrities as those who took the Ice Bucket Challenge for Lou Gehrig's disease, also known as ALS, it's stlll good to see some celebrities out there taking part.
