I'll just throw this one out there, don't crucify me:
Ooooooh ooh Steadinho, oooooh ooooh Steadinho, he's off to save the club, super super sub, Steadihno, oooooh oooh Steadinho, oooooh oooh Steadinho
Obviously the super sub thing is the only thing I could find that rhymes - maybe when he comes on as sub we could sing it, a situational chant
