Song performance starts at 3:59 of the video.
One of the coolest parts about Bonnaroo is the one-of-a-kind Superjam that brings together musicians who would normally never have an opportunity to play with each other. Last year, John Oates (of Hall & Oates) and Jim James (of My Morning Jacket) led an all-star band that played an epic late night set. Watch the video above for footage of their performance of T. Rex's "Bang A Gong (Get It On)" featuring Billy Idol.
One of the coolest things about these videos is that you get insight to the creative process for these performances. There are some really interesting interviews with the musicians talking about the performance and sharing their personal experiences and emotions throughout the landmark event. In the early days of Bonnaroo, these types of events were basically in the moment and not documented too thoroughly. It's very cool that they are putting videos like this together and sharing them with everyone for free on YouTube. Enjoy.
