I've got a Reservation

There's a land that I have been told
Where the streets are paved with gold
And the bright flowers bloom through all eternity
Mansions are glistening on that bright shore
Clearly this world could never afford
And I've got a reservation,
My names been written down!

Chorus:
I've got a reservation to walk on the streets of Gold
I've got a reservation when the pearly gates unfold
In heaven my names been written down
I'm longing to hear that trumpet sound
For I've got a reservation
My names been written down

There's a banquet table that's spread,
Filled with milk and honey and bread
Where we shall dine while the eternal ages roll
My friends and loved ones we'll meet there
Robbed in garments bright and fair
And I've got a reservation
My names been written down

I don't know who sung it originally but I heard the new Blackwood Brothers sing it.
