Proof that Britney DOES sing You Oughta Know and Don't Let Me Be the Last to Know Live

There is a lot of people who are saying that Britney did not sing Don't Let Me Be the Last to Know live on her Femme Fatale tour and that she did not sing You Oughta Know live on her Circus tour. This video is to prove those haters wrong. (if you want to see more songs she sang live then watch my video "New Britney Spears Singing and Dancing)

Obvious differences in the performances-
In Don't Let Me Be the Last to Know-
1. When she sings "they say you say we're so complete"- the first time she sings it in her high girly voice, the second time it is deep and strong, and the third time she sings it higher than the first
In You Oughta Know-
1. Her mic goes out the first night during the second verse and she completes the verse without the mic going out on the next night. She also does not sing "fuck her" on the first two nights and on the third night you can hear her sing "fuck her".

Yeah she is singing. stay mad.
