Conan O'Brien won't just be Tweeting over the next few months. The former "Tonight Show" host and overall funny-man needs to be brushing up his standup and MC'ing chops for his headlining slot at the Bonnaroo Music & Arts Festival and a 30-city theater tour.

CoCo will be the featured performer at the Comedy Theatre onsite at the fest in Manchester, Tenn., as well as keep audiences entertained between acts on the What Stage on Friday (June 11) and Saturday (June 12). The What Stage is the largest stage at the festival, with ground available for 100,000 people.

Margaret Cho, Aziz Ansari, Greg Giraldo, Bo Burnham, Doug Benson, Nick Kroll, Paul Scheer, Rob Huebel, John Roberts and Jeff Ross have also joined the Bonnaroo comedy sked, and will be roasting the festival itself.  Bonnaroo runs over four days, June 10-13 and includes musical headliners Dave Matthews Band, Jay-Z, Kings of Leon, Stevie Wonder, Weezer, Tenacious D and more.

As for the Legally Prohibited from Being Funny on Television Tour, Andy Richter and O'Brien's former "Tonight Show" band will join O'Brien for "a night of music, comedy, hugging and the occasional awkward silence."

The tour begins April 12 in Eugene, Ore. and has stops in Canada. As O'Brien says: "It was either a massive 30-city tour or start helping out around the house." Details can be had at TeamCoCo.com, tickets on sale now.

O'Brien's exit from NBC -- which included a $30+ million payout -- stipulates a non-compete clause which prevents him from returning to TV until after Sept. 1.
