Norton in 'exhausting' chat-a-thon
The newspaper said that the show will go out on BBC Three, from 7pm until Graham finally hangs up his microphone at 2am.
A show source was quoted as saying: "This will be the most exhausting thing Graham has ever done.
"Seven hours of live telly is no mean feat, so Graham is booking people he knows will lift his spirits."
Viewers will be able to text or ring in with donations during the chat-a-thon, which will take the same format as Graham's weekly BBC One chat show, but with guests being wheeled in and out.
