The Emmys released a statement revealing that there will be a special In Memoriam segment for actors James Gandolfini, Cory Monteith, Jean Stapleton, Jonathan Winters and producer David Goldberg.

"I always find the In Memoriam is just really interesting because sometimes it seems weird that they keep the audio on in the house, so some people get applause and some people don't, and it turns it into this weird moment," Harris, who is hosting the event for the second time told of the segment to Access Hollywood.

"And you want that moment to be honoring those people, and not a competition."

He elaborated: "We've come up with this idea -- five different people that we chose sort of from different areas of television are being spoken about by people who were important to them. [They'll speak about them] not in a pitying way, but I think in a respectful, classy way that will make you remember their life in a positive, forward-momentum kind of style."

Multi-Grammy Award winner Elton John will perform at the event, which will be a tribute to Liberace and other performances include Carrie Underwood marking the 50th Anniversary of US president John F Kennedy's assassination and The Beatles appearing on The Ed Sullivan Show.
