# We are no strangers to love

# You know the rules and so do I

# A full commitment′s what I am thinking of

# You wouldn′t get this from any other guy

# I just want to tell you how I am feeling

# Gotta make you understand

# Never gonna run around and desert you

# Never gonna make you cry never gonna say goodbye

# Never gonna tell a lie and hurt you

# We′ve known each other for so long

# Your heart′s been aching but You are too shy to say it

# Inside we both know what′s been going on

# We know the game and We are gonna play it

# And if you ask me how I am feeling

# Don′t tell me You are 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

# Never gonna give never gonna give give you up

# Never gonna give never gonna give give you up
