Glee Cast - Dancing Queen Lyrics
Send "Dancing Queen" Ringtone to your Cell 
You can dance
You can jive
Having the time of your life
See that girl
Watch that scene
Digging the Dancing Queen
Friday night and the lights are low
Looking out for the place to go
Where they play the right music
Getting in the swing
You come to look for a King
Anybody could be that guy
Night is young and the music's high
With a bit of rock music
Everything is fine
You're in the mood for a dance
And when you get the chance...
You are the Dancing Queen
Young and sweet, only seventeen
Dancing Queen
Feel the beat from the tambourine Oh Yeah!
You can dance
You can jive
Having the time of your life
See that girl
Watch that scene
Digging the Dancing Queen
You're a teaser, you turn them on
Leave them burning and then you're gone
Looking out for another, anyone will do
You're in the mood for a dance
And when you get the chance...
You are the Dancing Queen
Young and sweet, only seventeen
Dancing Queen
Feel the beat from the tambourine Oh Yeah!
You can dance
You can jive
Having the time of your life
See that girl
Watch that scene
Digging the Dancing Queen
Digging the Dancing Queen Send "Dancing Queen" Ringtone to your Cell
