like "chant" in place of "sing" because we say "sing" a line or two down anyway

how about:
we're newcastle
we're wonderful
we're gonna jump, clap & chant until we score
we're gonna win
and we will sing
the red, blue and gold is everything

i agree with militia - i think once we get to the fast pace, we stay fast. probably needs about 5 (?) slow reps though, so a couple to be introduced, a few as a big group, and then speed it up.
