Lời bài hát Happy Birthday

Ca sĩ: Năm Dòng Kẻ Album: Sắc Màu
Refrain:
Happy birthday to you, this is your day
On this day for you we're gonna love you in every way
This is your day, your day,
Happy birthday to you (to you), to you (to you), to you.

Happy birthday to you, you're still young
Age is just a number, don't you stop having fun
This is your day, your day, happy birthday to you
This day only comes once every year,
Because you're so wonderful with each and everything you do, hey...

(Refrain)

This day is only for you, 'cause you're so special in every way
Happy birthday to you!
