I Could Have Danced All Night (Glee Cast Version) 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
