The Cumberland Guard like many Civil War era units developed its own marching song. This song is sung to the tune of "She Wore a Yellow Ribbon."

God Wears A Light Blue Ribbon

Way up in heaven God Wears a Light Blue Ribbon
He wears a Light Blue Ribbon and he wears it very proud
Saint Peter asked, "Lord, Why the Light Blue Ribbon?"
He said he wears the Ribbon for the Cumberland Guard

Cumberland, Cumberland! Cumberland, Cumberland!
God Wears a Light Blue Ribbon for the Cumberland Guard
Cumberland, Cumberland! Cumberland, Cumberland!
God Wears a Light Blue Ribbon for the Cumberland Guard

Saint Peter looked at all of Heaven's Soldiers
To find a Light Blue Ribbon, It wasn't very hard
There were Grant and Sheridan and Sherman
All wearing Light Blue Ribbons for the Cumberland Guard

Cumberland, Cumberland! Cumberland, Cumberland!
God Wears a Light Blue Ribbon for the Cumberland Guard
Cumberland, Cumberland! Cumberland, Cumberland!
God Wears a Light Blue Ribbon for the Cumberland Guard

Cumberland, Cumberland! Cumberland, Cumberland!
God Wears a Light Blue Ribbon for the Cumberland Guard
Cumberland, Cumberland! Cumberland, Cumberland!
God wears a Light Blue Ribbon for the Cumberland Guard

When I die, I hope to go to Heaven
With Saints in my Battalion and an Angel for my Pard
I'll March with John Brown in the Army of the Lord
and Wear a Light Blue Ribbon for the Cumberland Guard

Cumberland, Cumberland! Cumberland, Cumberland!
God Wears a Light Blue Ribbon for the Cumberland Guard
Cumberland, Cumberland! Cumberland, Cumberland!
God wears a Light Blue Ribbon for the Cumberland Guard
