This is the third track on American alternative rock band The Dead Weather's debut album, Horehound. The band consists of The Kills' Allison Mosshart on vocals, Queens Of The Stone Age multi-instrumentalist Dean Fertita taking care of guitar duties, The Raconteurs' Jack Lawrence on bass and White Stripes/ Raconteurs' Jack White thumping the drums.
On this track White joins Mosshart on vocals, where he swops his usual high pitched yelp for a deeper voice.
This was the lone track on Horehound that White wrote by himself.
The Flaming Lips' "Do You Realize??" was named in March 2009 the official Rock Song of Oklahoma. Four years later, Oklahoma's governor Mary Fallin pulled the tune as the state's official rock song in a move her office said had more to do with priorities than musical taste.
The lyrics for "Mary, Did You Know?" were written by Christian singer and comedian Mark Lowry, after his pastor asked him to write a Christmas musical for their church. Southern gospel musician Buddy Greene later added music to his words.
