　　Oh I wanna dance with somebody

　　I wanna feel the heat with somebody

　　Yeah Wanna dance with somebody

　　With somebody who loves me

　　I want to dance

　　Clocks strikes upon the hour

　　And the sun begins to fade

　　Still enough time to figure out

　　How to chase my blues away

　　I've done alright up'til now

　　It's the light of day that shows me how

　　And when the night falls

　　My loneliness calls

　　Oh I wanna dance with somebody

　　I wanna feel the heat with somebody

　　Yeah I wanna dance with somebody

　　With somebody who loves me

　　I wanna dance with somebody

　　I wanna feel the heat with somebody

　　Yeah Wanna dance with somebody

　　With somebody who loves me

　　I've been in love and lost my senses

　　Spinning through the town

　　Sooner or later the fever ends

　　And I wind up feeling down

　　I need a man who'll take a chance

　　On a love that burns hot enough to last

　　So when the night falls

　　My loneliness calls

　　Oh I wanna dance with somebody

　　I wanna feel the heat with somebody

　　Yeah Wanna dance with somebody

　　With somebody who loves me

　　Oh I wanna dance with somebody

　　I wanna feel the heat

　　Yeah Wanna dance with somebody

　　With somebody who loves me

　　Somebody who

　　Somebody who

　　Somebody who loves me yeah

　　Somebody yeah

　　To hold me in his arms

　　I need a man who'll take a chance

　　On a love that burns hot enough to last

　　So when the night falls

　　My lonely heart calls

　　Oh I wanna dance with somebody

　　I wanna feel the heat with somebody

　　Yeah Wanna dance with somebody

　　With somebody who loves me

　　Oh I wanna dance with somebody

　　I wanna feel the heat

　　Yeah Wanna dance with somebody

　　With somebody who loves me

　　Don't you wanna dance

　　Don't you wanna dance

　　Don't you wanna dance

　　With somebody who loves me

　　Don't you wanna dance

　　Say you wanna dance

　　Don't you wanna dance

　　Don't you wanna dance

　　Say you wanna dance

　　Don't you wanna dance

　　Say you wanna dance

　　With somebody who loves me

　　Don't you wanna dance

　　Say you wanna dance

　　With somebody who love

　　I wanna dance with somebody
