    B
I?m living for the weekend but know ? more
Em
Cause she comes that for me your feeling That Friday?s famous for
B
Yeah, I?m looking for some action
Em
And it?s out there somewhere You can feel the electricity, on and in the air
B
And it may be just more off the same

So I guess I?ll have to wait and see
Em
But I?m just gonna let something brand new happen to me

the rest is the same: B Em...

Friday's cool but there's something about Saturday night
You can't say what you won't do cause you know you just might
Our lives this evening it was love at first sight
This Saturday and every Saturday for the rest of my life
And everyone standing in line
Yeah, looking good and looking for a real good time
And I never had to wonder if 
I'll have someone to share out of this wish

Chorus:
And it's all right, it's all right, it's all right, it's all right, it's all right
Bright lights bigger city belongs to us tonight, tonight

Guess I need it, everybody does
Got tells and conversation, music and making love

Chorus:
And it's all right, it's all right, it's all right, it's all right, it's all right
Bright lights bigger city belongs to us tonight, tonight X 2
