I thought it was awesome. He's a living legend among music circles. What songs did he play (in order)? I think I missed the first two, but I heard:
Drive My Car
Get Back
Hey Jude
Live and Let Die
Get Back was awesome to hear live. One of the greatest tragedies of rock is that The Beatles didn't do any live shows after 1966, and the recording equipment around back then really didn't capture just how good they were live. Some of those later songs like Get Back are flat out awesome live. The Apple Rooftop Jam was proof of that.
IMO, the people b&tching about the halftime show really just don't know anything about rock and roll. That was possibly the best Super Bowl Halftime show ever.
