The sheet music:
Accompaniment by James Pitt-Payne:
Lyrics
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
Refrain
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
Sung here by Fred Feild:
