May Day - Wikipedia

Now Is the Month of Maying
Now is the month of Maying, 
When merry lads are playing! 
Fa la la la la!

Each with his bonny lass, 
A-dancing on the grass, 
Fa la la la la! 

The Spring, clad all in gladness, 
Doth laugh at Winter's sadness! 
Fa la la la la!

And to the bagpipes’ sound, 
The nymphs tread out the ground! 
Fa la la la la!

Fie! Then why sit we musing, 
Youth’s sweet delight refusing? 
Fa la la la la!

Say, dainty nymphs and speak! 
Shall we play barley break
Fa la la la la! 

Sir Thomas Morley
