I. 
  I laugh and sing, but cannot tell 
  Whether the folly on't sounds well; 
               But then I groan, 
               Methinks, in tune; 
Whilst grief, despair and fear dance to the air 
          Of my despised prayer. 
 
                      II. 
  A pretty antick love does this, 
  Then strikes a galliard with a kiss; 
               As in the end 
               The chords they rend; 
So you but with a touch from your fair hand 
          Turn all to saraband.
Richard Lovelace
