Lyrics:

When our time is up,
When our lives are done,
Will we say we've had our fun?

Will we make a mark,
This time.
Will we always say we tried?

Standing on the rooptops,
Everybody scream your heart out.
Standing on the rooptops,
Everybody scream your heart out.
Standing on the rooptops,
Everybody scream your heart out.
This is all we've got now,
Everybody scream your heart out.

All the love I've met,
I have no regrets,
If it all ends now,
I'm set.

Will we make our mark,
This time.
Will we always say we tried?

Standing on the rooftops,
Everybody scream your heart out.
Standing on the rooftops,
Everybody scream your heart out.
Standing on the rooftops,
Everybody scream your heart out.
This is all we've got now,
Everybody scream your heart out.

Standing on the rooftops,
Waiting till the bomb drops,
This is all we've got now,
Scream until your heart stops,
Never gonna regret,
Watching every sunset,
Listen to your heartbeat,
All the love that we've felt.

Standing on the rooftops,
Waiting till the bomb drops,
This is all we've got now,
Scream until your heart stops,
Never gonna regret,
Watching every sunset,
Listen to your heartbeat,
All the love that we've felt.

Scream your heart out.
Scream your heart out.
Scream your heart out.
Scream your...

Standing on the rooftops,
Everybody scream your heart out.
Standing on the rooftops,
Everybody scream your heart out.
Standing on the rooftops,
Everybody scream your heart out.
This is all we've got now,
Everybody scream your...
