Hello;
Glad it is of some help. On the words "we come to clap our hands and give Him praise" where it says "OR", the chords on the left can be used, or the 2-5-1 on the right. I just use pedal with the 2-5-1. They both will fit that phrase. Or I use one one time and one the other. As for the "glo-ry glo-ry", I play the chords exactly with those syllables. The Fill part is just one that I use. Hope that is helpful.
