first half of naam yi deuong ji keoung, now we can all sing along.

O hei o siu man chung long
Defiantly facing insurmountable odds

Yit huet yit sing hung yat gwong
Burning with righteous spirit like this red sunlight

Daam si tit da
With resolute courage

Gwat ji jing gong
With an uncompromising character

Hung kam baak chin jeung
With the broadest mind

Ngaan gwong maan lei cheung
With a far-sighted vision

Sai fen yiu faat ji keung
I go all out to make the country strong

Jo goh ho hon ji
In order to be a great hero

Mui tin yiu ji keung
Every day you must push yourself

Yit huet naam ji
The righteous spirit of a hero

bit sing hung yat gwong
burns brighter than the sun

Yeung hoi tin wai ngoh jeui neng leung
Sea and sky yield their power for me to gather

the last line here is the part where u say george lam stretches his vocals to the point of breaking, quan LOL.
