We're no strangers to love

A full commitment's what I'm thinking of

You wouldn't get this from any other guy

I just want to tell you how I'm feeling

Gotta make you understand

Never gonna give you up, never gonna let you down

Never gonna run around and desert you

Never gonna make you cry, never gonna say goodbye

Never gonna tell a lie and hurt you

Your heart's been aching but you're too shy to say it

Inside we both know what's been going on

We know the game and we're gonna play it

And if you ask me how I'm feeling

Don't tell me you're too blind to see

Never gonna give you up, never gonna let you down

Never gonna run around and desert you

Never gonna make you cry, never gonna say goodbye

Never gonna tell a lie and hurt you

Never gonna give you up, never gonna let you down

Never gonna run around and desert you

Never gonna make you cry, never gonna say goodbye

Never gonna tell a lie and hurt you

Ooh, give you up

Ooh, give you up

(Ooh) Never gonna give, never gonna give (Give you up)

(Ooh) Never gonna give, never gonna give (Give you up)
