[Verse 1]
Who knows your birthday?
Who knows your number?
Who knows your color?
Who knows your hands?
Who knows the sum?
The sum of all your parts

[Verse 2]
Who knows your limit?
Who knows your highest?
Who knows your lowest?
Who knows your end?
Who knows that bottom?
The bottom of your heart

[Chorus]
Hold on, hold on
Keep holdin' on to me
I will love you from the bottom
No one holds you better than me

Hold on, hold on
Doing the best we can
I will love you on your birthday
I will love you better than them
[Verse 3]
Who knows the reason?
Who knows the cure?
Who knows the answer?
Who knows the cause?
Who knows the pain?
The pain when we're apart

[Chorus]
Hold on, hold on
Keep holdin' on to me
I will love you from the bottom
No one holds you better than me

Hold on, hold on
Doing the best we can
I will love you on your birthday
I will love you better than them
