Is that the song that goes...
Chorus:
We come to lift our hands and glorify him
We come to lift our hands and give him praise
(repeat)
Give him glory, Give him glory
We come to lift our hands and give him praise
Give him glory, give him gloryyyyyy
We come to lift our hands and give him praise
(Sing the chorus again, but you change " we come to lift our hands and glorify him" to "we come to lift our voice and sing of Judah" and " We come to clap our hands and magnify him")
Vamp:
(hint: they are breaking up the word Hallelujah)
Alto:Halle
Everyone: Halle
Alto: Lujah
Everyone: Lujah
(repeat, and take the key up as necessary)
If I am wrong about the song, I'm sorry, but that's the only song I knew that sounded like that, and those are the words I remember. Also, if I remember, it has the same sound as "Come on and bless the Lord with me." Not the exact6 chords, but the same sort of flow.
