Asking people in the audience to sing along - yes or no?

[Enaillid]

I am singing in a vocal competition in a few weeks. One of the songs I will be singing is "This Ain't A Scene, It's An Arms Race" by Fall Out Boy. Near the end of the song they ask the audience to sing back to them, which I think is pretty cool. It's a relatively popular song, so I am assuming a good number of people will recognize it. I would also like to ask the tech guys to project the lyrics the audience is supposed to sing onto a screen. I discussed this with some people, and they said not to do it because people in audiences generally don't want to participate in performances. Keeping in mind that this is a college performance, performed and attended by college students, do you think this is true? Should I risk the awkward silence, or just go for it?

It's supposed to be you performing but the judges might award extra points if you're able to get the audience going.
