My top 5 (only the intro, not the first performance)
1. Re-Invention Tour
2. Confessions Tour
3. Sticky And Sweet Tour
4. Blond Ambition Tour
5. MDNA Tour
We already know the lyrics, even if it's re-working, there is a risk that the demos are preferred to final versions knowing that they leaked before, it would be a problem....
