"The Old Rugged Cross" was a hymn that the New Earth inhabitants stuck in the Motorway sang together on the day the Tenth Doctor and Martha Jones arrived.

Its lyrics included:

On a hill far away stood an old rugged cross
The emblem of suffering and shame
And I love that old cross where the dearest and best
For a world of lost sinners was slain
So I'll cherish the old rugged cross
'Till my trophies at last I lay down
I will cling to the old rugged cross
And exchange it some day for a crown
