[Verse 1: Tim & Nathan, Charli, Sun & Kellie, All]
I’ll run for a mile
I’ll laugh all day
I’ll shout from the highest hill
I’ll swing from a tree
Kick my heels up high
I just can’t keep still

[Pre-Chorus: All]
Feeling happy, feeling good

[Chorus: All]
Happy, happy, I’m so happy
Can’t believe I feel so happy
Must be something special about today
Happy, happy, I’m so happy
Can’t believe I feel so happy
Must be something special on the way
'Cause I feel so happy today

[Verse 2: Tim & Nathan, Charli, Sun & Kellie, All]
There’s a spring in my step
A bounce in my walk
And I can jump up ten feet high
When I woke up today
I had one thing to say
It’s gonna be a wonderful day
[Pre-Chorus: All]
Feeling happy, feeling good

[Chorus: All]
Happy, happy, I’m so happy
Can’t believe I feel so happy
Must be something special about today
Happy, happy, I’m so happy
Can’t believe I feel so happy
Must be something special on the way
'Cause I feel so happy today

[Verse 2: All, Tim, All]
Hap-hap-hap-hap-hap-hap-hap-hap-happy
Nothing's gonna change my mood
Hap-hap-hap-hap-hap-hap-hap-hap-happy
'Cause I'm feeling so good!
Yeah, we’re feeling so

[Chorus: All]
Happy, happy, I’m so happy
Can’t believe I feel so happy
Must be something special about today
Happy, happy, I’m so happy
Can’t believe I feel so happy
Must be something special on the way
'Cause I feel so happy
Feel so happy today
[Outro: All]
'Cause I feel so happy today!
