Sing Ladybird Sing

I hear birds sing Beautifully they sing With bliss they cheer the sun as it rises from the mountains I hear them sing every hour of the morning With confidence they sing their different melodies Summer or winter spring or autumn Still they sing their music well tuned it has my ears open all the time Their tone so smooth it shoots sleep out of the bed I hear that they sing with perfection and beauty And still I don't know why they sing Still I hear them sing with so much beauty and confidence Then I wonder if they have a stage or an audience Or they just sing for the bliss of it.
