Hi. I know the human rights org. I belong to has shown this video several times. I cannot remember the song and the people who would are out of town for the weekend. By Monday, if no one else has been able to help you, I'll at least be able to find out where you might be able to find lyrics.
I checked the websites of Southern Poverty Law Center's Teaching Tolerance and also that of the Northwest Coalition Against Malicious Harassment, to no avail.
I see what I can do on Monday.
