I Could Have Danced All Night (From "My Fair Lady")

Bed, bed! I couldn't go to bed
 My head's too light to try to set it down
 Sleep, sleep! I couldn't sleep tonight
 Not for all the jewels in the crown
 I could have danced all night
 I could have danced all night
 And still have begged for more
 I could have spread my wings
 And done a thousand things
 I've never done before
 I'll never know what made it so exciting
 Why all at once my heart took flight
 I only know when he began to dance with me
 I could have danced, danced, danced all night
 ♪
 I could have danced all night (You're tired out, you must be dead)
 I could have danced all night (Your face is drawn, your eyes are red)
 And still have begged for more (Now say goodnight, turn out the light)
 (Please, it's really time for you to be in bed)
 I could have spread my wings (Do come along, do as you're told)
 And done a thousand things (Or Mrs. Pierce is apt to stir)
 I've never done before (You're up too late, please, it sure is late)
 (Miss, you'll catch a cold)
 I'll never know what made it so exciting
 Why all at once my heart took flight
 I only know when he (Put down your book, the work'll keep)
 Began to dance with me (Now settle down and go to sleep)
 I could have danced, danced, danced all night
