Oenone:

Fair and fair, and twice so fair, 
As fair as any may be; 
The fairest shepherd on our green, 
A love for any lady. 

Paris:

Fair and fair, and twice so fair, 
As fair as any may be; 
Thy love is fair for thee alone 
And for no other lady. 

Oenone:

My love is fair, my love is gay, 
As fresh as bin the flowers in May 
And of my love my roundelay, 
My merry, merry, merry roundelay, 
Concludes with Cupid's curse,-- 
'They that do change old love for new 
Pray gods they change for worse!' 

Ambo Simul:

They that do change old love for new, 
Pray gods they change for worse! 

Oenone:

Fair and fair, and twice so fair, 
As fair as any may be; 
The fairest shepherd on our green, 
A love for any lady. 

Paris:

Fair and fair, and twice so fair, 
As fair as any may be; 
Thy love is fair for thee alone 
And for no other lady. 

Oenone:

My love can pipe, my love can sing, 
My love can many a pretty thing, 
And of his lovely praises ring 
My merry, merry, merry roundelays 
Amen to Cupid's curse.
