Do I love you because you're beautiful?

A Rodgers and Hammerstein favourite of mine. 

Do I love you because you're beautiful,
or are you beautiful because I love you?
Am I making believe I see in you
a girl too lovely to be really true?

Do I want you because you're wonderful,
or are you wonderful because I want you?
Are you the sweet invention of a lover's dream
or are you really as beautiful as you seem?

Am I making believe I see in you 
a man too perfect to be really true?
Do I want you because you're wonderful,
or are you wonderful because I want you?

Are you the sweet invention of a lover's dream 
or are you really as wonderful as you seem?
