[Intro]
Oh, oh-oh-oh-oh-oh-oh, oh-oh-oh-oh-oh-oh, oh, oh, oh, oh, oh
Oh, oh-oh-oh-oh-oh-oh, oh-oh-oh-oh-oh-oh, oh, oh, oh, oh, oh

[Verse 1]
I’d fallen through the floor again
Crashed into the basement
The pain was swallowing me
I was like a lead balloon
I couldn’t even get up to
Turn the lights on
The dark is swallowing me

[Pre-Chorus]
Lord knows you can’t trust your head
When you’re standing on the edge
Of breaking down
Lord knows you can’t trust your head
When you’re hanging by a thread
I was breaking down, and I saw…

[Chorus]
Only two footprints in the sand
Thought you’d abandoned me and
Let go of my hand
But you were carrying me,
Carrying me to safety
Two footprints, your footprints in the sand
Two footprints, two footprints, your footprints in the sand
Two footprints, your footprints in the sand

[Verse 2]
Oh, I forgot the things I knew
It was I who’d abandoned you
Forgive me, I was lost in doubt
You had never left my side
Picked me up when I thought I might die
You held me and I was found

[Pre-Chorus]
Lord knows you can’t trust your head
When you’re standing on the edge
Of breaking down
Lord knows you can’t trust your head
When you’re hanging by a thread
When you’re breaking down…

[Chorus]
Only two footprints in the sand
Thought you’d abandoned me and
Let go of my hand
But you were carrying me,
Carrying me to safety
Two footprints, your footprints in the sand

Only two footprints in the sand
Thought you’d abandoned me and
Let go of my hand
But you were carrying me,
Carrying me to safety
Two footprints, your footprints in the sand
Two footprints, two footprints, your footprints in the sand
Two footprints, your footprints in the sand.
