Wango Tango Concert and the duet with her sister?

[i_survived_disturbia]

I didn't get to watch or tape the Wango Tango concert and I was wondering what songs Hilary sang? I didn't know what day it was on and so I didn't get to tape it. Also, I was trying to find out what time the making of the video for "Our Lips Are Sealed" would be on on Monday, but all the info said was "Hilary Duff" and nothing about it being a duet with her sister. I'm hoping it's the right one. Don't you think it would say something about being a duet with her sister?

I dont know I was hoping SOMEONE would put up a video! Dirrty!
