For we will rock you, One alto singer can start us off (this is quite similar to my lean on me idea) the alto singer can sing "Buddy, you're a boy, make a big noise, playing in the street, gonna be a big man someday" and then the drums and lights would flash and fades back to silence and darkness with only one light shining at the singer. Then instead of the next line all singers sing "We will, we will rock you" using chest voice then another singer continues/finishes the "You got mud on your face, you big disgrace, kicking your can all over the place, singing then "we will, we will rock you" everyone sings using chest voice.
