(Video) Virtual Choir: ♫ The evening hangs ♫ ♫ beneath the moon ♫ ♫ A silver thread on darkened dune ♫ ♫ With closing eyes and resting head ♫ ♫ I know that sleep is coming soon ♫ ♫ Upon my pillow, ♫ ♫ safe in bed, ♫ ♫ a thousand pictures fill my head ♫ ♫ I cannot sleep ♫ ♫ my mind's aflight ♫ ♫ and yet my limbs seem made of lead ♫ ♫ If there are noises in the night ♫
