Leno Letterman Opera Superbowl TV Advert 

Assuming that this event needs mention on Leno's page, and IMO I think not, the current phrase addressing it is completely misplaced by being under the "Criticism of Leno” section, and additionally, it seems tagged onto a sentence that is unrelated so that the sentence reads terribly.  For ease of reference it appears under that section thusly:

Bill Zehme, the co-author of Leno's autobiography Leading with My Chin, told the LA Times: "The thing Leno should do is walk, period. He's got everything to lose in terms of public popularity by going back. People will look at him differently. He'll be viewed as the bad guy,"[46] and two weeks later, appeared alongside Winfrey and his television rival David Letterman in an ad for Late Show with David Letterman that aired during the Super Bowl.
