Americas Voice News mentioned that before the walkout music (God Bless the USA) they were playing Metallica- Enter Sandman. The hosts mentioned this was the first time they heard it af a rally. Given the lyrics, I find this VERY interesting :

Say your prayers, little one Don't forget, my son To include everyone I tuck you in, warm within Keep you free from sin 'Til the Sandman, he comes Sleep with one eye open Gripping your pillow tight Exit light, what is it? (Enter night) Take my hand We're off to never-never land Yeah, yeah Something's wrong, shut the light Heavy thoughts tonight And they aren't of Snow White Dreams of war, dreams of liars Dreams of dragon's fire And of things that will bite, yeah Sleep with one eye open Gripping your pillow tight Exit light, come on (Enter night) Take my hand We're off to never-never land Oh yeah Put your hands together Now I lay me down to sleep (now I lay me down to sleep) Pray the Lord my soul to keep (pray the Lord my soul to keep) If I die before I wake (if I die before I wake) Pray the Lord my soul to take Hush little baby, don't say a word And never mind that noise you heard It's just the beasts under your bed In your closet, in your head Exit light, come on (Enter night) Grain of sand Exit light Enter night Take my hand Off to never-never land Yeah, yeah, yeah We're off to never-never land Take my hand We're off to never-never land Take my hand We're off to never-never land

So many Q refernences....I see this as comms, I like to think of it as a warning to the DS "sleep with one eye open,griping your pillow tight".
