Is anyone worried we might get Justin Timberlake'd? Not sure if Bonnaroo would go after him, but it would be a 'rare' festival appearance.
Financially, a "McCartney - Justin Timberlake - INSERT JAM BAND HERE" top 3 sounds very feasible considering how much Macca would likely cost.
Just a thought, and not sure how he is live, but I may enjoy that more than Mumford.
I was ridin the Timberlake hate train for a good while but I had to stop after I saw his HBO special concert a few years ago. I put it on for a laugh and I couldn't stop watching. Clearly the guy can sing and dance but he was also playing piano and a couple other instruments, he jammed some blues songs, had some great guests on stage with him, totally entertaining. I'd rather get a different artist but if we get JT'd I think it will be pleasantly surprising for most people.
