DING DONG! 
MERRILY ON HIGH

Ding dong! Merrily on high
In heav'n the bells are ringing
Ding dong! Verily the sky
Is riv'n with angel singing

Gloria, Hosanna in excelsis!
Gloria, Hosanna in excelsis!

E'en so here below, below
Let steeple bells be swungen
And i-o, i-o, i-o
By priest and people sungen

Gloria, Hosanna in excelsis!
Gloria, Hosanna in excelsis!

Pray you dutifully prime
Your matin chime, ye ringers
May you beautifully rime
Your evetime song, ye singers

Gloria, Hosanna in excelsis!
Gloria, Hosanna in excelsis!
