Classic hymn heard in Season 3 episode 'Gridlock'

Abide with me; fast falls the eventide;
The darkness deepens; Lord, with me abide;
When other helpers fail, [bad word] flee,
Help of the helpless, Lord abide with me.

Swift to its close ebbs out life’s little day;
Earth's joys grow dim, its glories pass away;
Change and decay in all around I see;
O Thou, Who changest not, abide with me.
