Someone please help me with this.

So.
I was listening to "Johnny Are You Queer"(Josie Cotton), and I was looking up covers of it and stuff, and I came along this Video.

so. . .if you could help me with this -
1)Who are the dudes rapping with her,
2)What exactly is all of what they're saying? I can only make out bits.

Please help me out here(;
