Analysis of The Matin-song of Friar Tuck

I.
If souls could sing to heaven's high King
As blackbirds pipe on earth,
How those delicious courts would ring
With gusts of lovely mirth!
What white-robed throng could lift a song
So mellow with righteous glee
As this brown bird that all day long
Delights my hawthorn tree.
Hark! That's the thrush
With speckled breast
From yon white bush
Chaunting his best,
 Te Deum! Te Deum laudamus!

II.
If earthly dreams be touched with gleams
Of Paradisal air,
Some wings, perchance, of earth may glance
Around our slumbers there;
Some breaths of may might drift our way
With scents of leaf and loam,
Some whistling bird at dawn be heard
From those old woods of home.
Hark! That's the thrush
With speckled breast
From yon white bush
Chaunting his best,
 Te Deum! Te Deum laudamus!

III.
No King or priest shall mar my feast
Where'er my soul may range.
I have no fear of heaven's good cheer
Unless our Master change.
But when death's night is dying away,
If I might choose my bliss,
My love should say, at break of day,
With her first waking kiss:--
Hark! That's the thrush
With speckled breast,
From yon white bush
Chaunting his best,
 Te Deum! Te Deum laudamus!
