Answer 2

Got To Give It Up (lyrics)

I used to go out to parties
and stand around
'cause I was too nervous
to really get down
but my body yearned to be free
I got up on the floor and thought
somebody could choose me
No more standin' there beside the walls
Finally got myself together baby
and I'm havin' a ball
As long as you're groovin'
there's always a chance
somebody watches
and might wanna make romance
Move your body, ooo baby, you dance all night
to the groove and feel alright
Everybody's groovin' on like a fool
But if you see me spread out and let me in
Baby just party high and low
Let me step into your erotic zone
Move it up
Turn it 'round
ooo Shake it down
OOWW
You can love me when you want to babe
This is such a groovy party baby
We're here face to face
Everybody's swingin'
This is such a groovy place
All the young ladies are so fine
You're movin your body easy with no doubts
I know what you thinkin' baby
you wanna turn me out
I think I'm gonna let you do it babe

Keep on dancin'
You got to get it
Got to give it up
(repeat until end)
