Well for the city of Philadelphia, apparently one huge, life-changing concert wasn't enough. We demand more and somehow got it in the form of Elton John. Just 2 days after Live8 on the 4th of July, Elton John is playing on the same Live8 stage, with the same sound, same screens, etc. A few other performers will be joining him such as Bryan Adams. But Elton is trying to raise awareness of the global AIDS/HIV crisis. So at least both concerts send a message.
