I just stumbled across this. From the outfit she's wearing in both
these photos and the
video of her singing , it seems to me that the video must be from the Block Party on Wisteria Lane from April 2011.
I love seeing Teri sing. She's so adorable!
Edit:
Oooh lala! I found some more!
One - This one has a sound malfunction half way through, so I suggest turning your volume down a bit.
This is the same performance as above, but from another camera and further away.
