Do you love the Purple Haze? Can't get enough of their amazing a cappella sound? Or maybe you just have no idea who they are?
Neither did we, until Penn Quarter Living pointed out the group from Northwestern U. will be singing a mix of Christmas carols and pop music for free outside of Ford's Theatre tonight from 6:30 p.m. to approximately 7:20 p.m.
That's right before "A Christmas Carol" -- the show you do have to buy tickets for -- starts.
