Honestly, to date (Only 25 years old).
The best all around Super Bowl halftime show I can remember was in 2001 with Aerosmith, Britney Spears and N'Sync.
I thought it was a good mix of different generas and was more centered on the music and singing rather than putting on a dance production.
Wouldn't mind seeing another colaboration of big time artists again. No more of this single act shows.
Maybe, Lady Gaga...Metallica...Drake combo.
