Chorus:
It's happy day, it's happy time
We all live, we all die, we all scream
Verse 1:
It's the day when you live and you dream
No more pain, no more crying
No more sadness, no more fears
You're safe now, you're alright
Chorus:
It's happy day, it's happy time
We all live, we all die, we all scream
Bridge:
This is the moment you've been waiting for
This is the day you rise up and soar
This is the time when you take control
And make your dreams come true
Chorus:
It's happy day, it's happy time
Time to shine, we're all in this together
Yeah! (x2)
Chorus to end:
It's happy day, it's happy time (Happy time)
Time to embrace life and give a sigh of relief.
