Here are the lyrics I remember:

Some people go on weekdays to D A N C E
They go to church on Sunday to show their H A T
They dub their faces up with P A I N T
And then they laugt at us because we're F R double E
oooooh G L O R Y, we're F R E E
We're H A P P Y to be F R E E
We're S A V E D from the bonds of S I N
Glory, glory halleluia,
tra la la amen!
