Yesterday was a big news in the comedy world with Conan O’Brien announcing that he’s taking his former lineup at The Tonight Show — namely himself, Andy Richter, and The Tonight Band with Max Weinberg — all on the road for a huge cross-country tour. Right around the same time I got this news and snagged myself a ticket for one of his dates in San Francisco, the promoters over at Bonnaroo had announced their Comedy Tent headliners for the 2010 festival. Guess who’s at the top of the bill?

The festival will welcome some of the most hilarious personalities working today, including Conan O’Brien, who not only will be performing in the Comedy Theatre, but will also be MCing the What Stage on Friday and Saturday.

Read on for the comedy lineup, which joins an already stellar music lineup announced last month.
