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

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 known what made it so exciting
why all at once may heart took flight
I only known when he began to dance with me
I could have danced
danced
danced all night.
