The second DVD has nearly the complete show for 2006, which was staged to help victims of Hurricane Katrina and rebuild New Orleans. This DVD's chapters are actually an index of performances that allows you to choose which ones to watch. The "extras" are parts of the telethon left out of the main presentation on the DVD: non-comedy stories about New Orleans, Billy Crystal's tribute to the city, Wayne Brady's improv rap song from a stage in New Orleans, and the introduction of celebrities involved in "Comic Relief Wild," the next planned show. (After a cursory search of the web, I could not verify that this show has ever taken place.) I guess if you only want to watch comedians, some of the "extras" would make you impatient. But they are just parts of the show that were cut from the main sequence. I think it would have been fine to include them and actually provide some traditional DVD extras, like interviews or behind-the-scenes footage, both of which are completely lacking.
So, in my opinion, only Comic Relief devotees and historians of humor need apply for watching these DVDs. I would love to know if someone most devoted to the form of stand-up comedy would disagree. Actually, I hope they would. Someone should say something nice.
