Martin Garrix and U2 “Fireflies” song lyrics

Few expected one of the biggest surprises of Tomorrowland Belgium to come from U2. During Martin Garrix's headline set at the festival in Boom, Antwerp, fans were treated to the debut of a previously unheard track, "Fireflies," credited in performance footage to Martin Garrix and U2. 

The appearance became even more significant when The Edge joined Garrix on stage, while Bono's unmistakable vocals carried the song. 

U2 song lyrics: Fireflies

I can feel, I can breathe

I can feel the undertow

I can hear the river flow

Laughing at us as we go

The present and the vanishing

The divine in everything

In the air, your summer dress

Has left me floating

And I can never keep a secret

Everything is always known

Nothing here is ever hidden

Cause everything is all we show

I can never keep a secret

I don’t know why I'd even try

We’rе looking through a sky of mirrors

To see ourselves tonight

Cause you and I arе fireflies

More for the sun and skies

The light that's in each other eyes

Fireflies

You and I are fireflies

Forgetting that the sun will rise

I met you in the air tonight

Fireflies

Fireflies

Fireflies

We can hurt or we can mend

Terrorize or transcend

No beginning, and no end

Yeah, you’ll survive

Like falling angels bound to earth

Voices sing for all they're worth

All I need is a pen that works

But it's a story without words

Of how the night will set us free

Take us where we need to be

Your waking eyes are all I need

I feel your life

But I can never keep a secret

Everything is always known

Nothing here is ever hidden

Cause everything is all we show

I can never keep a secret

I don’t know why I'd even try

We’re looking through a sky of mirrors

To see ourselves tonight

Cause you and I are fireflies

More for the sun and skies

The light that's in each other eyes

Fireflies

You and I are fireflies

Forgetting that the sun will rise

I met you in the air tonight

Fireflies

We can hurt or we can mend

Terrorize or transcend

No beginning, and no end

Yeah, you're alive

The collaboration immediately sparked speculation among fans: is "Fireflies" simply a one-off partnership between the Dutch DJ and Ireland's biggest rock band, or could it offer an early glimpse into U2's long-awaited next studio album? 

 This writer suspects it is a song for Garrix's new album rather than a song that will be on the U2 record.

 I can feel I can move I can feel the undertow I can hear the river flow Laughing at us as we go The present and the vanishing The Divine in everything In the air your summer dresses left me floating Fireflies, you and I are fireflies Fireflies, you and I are fireflies 

 Eagle eyed (!) listeners will note that fireflies is mentioned in City of Blinding Lights. Check out Silencio and Street of Dreams.
