Most people who will buy the new Band Aid single have no idea who Bob Geldof is, according to the man behind the video for the song.
Do most young people know who Bob Geldof is?
Do They Know It's Christmas? by Band Aid 20, is a remake of the original 1984 song, written by Bob Geldof and Midge Ure.
A host of top names recorded a soon-to-be-released new version of the song.
But Newcastle-born TV producer Malcolm Gerrie, admitted many young people are
unaware of the Irishman's achievements.
Joss Stone, Robbie Williams, Snow Patrol, The Darkness and The Sugababes, are among the stars taking part in Band Aid 20.
Mr Gerrie, chief executive of independent production company Initial, and fellow North East filmmaker Geoff Wonfor were behind the video for the original song in 1984.
They were again asked to record the event for a promotional video and a BBC documentary.
But Mr Gerrie, who created The Tube for Channel Four, said: "I'm sure that many people won't know who Bob Geldof is.
Malcolm Gerrie produced the Band Aid videos
"I had to explain to my 14-year-old son who he was and what he had done with Band Aid and Live Aid.
"And even Joss Stone said when she arrived for the recording, that she was really excited to meet Gandalf."
Mr Gerrie said of the new version: "It is absolutely brilliant.
"I think what's brilliant about it is the way a lot of contemporary talent has been brought in and the way new kinds of music have been used.
"Basically this is the crème de la crème of the new contemporary artistes."
The new Band Aid single was broadcast on radio for the first time on Tuesday.
The song will raise money for food aid in Darfur, Sudan, when it is commercially released on 29 November.
The video, which premieres on BBC One on Thursday, also features stars including Will Young, Jamelia, Busted and the return of Bono from U2 who sang on the original record.
Band Aid was organised by Geldof after he saw news footage of the starving in Ethiopia.
Retailers expect to sell about 500,000 copies in its first week.
Woolworths and Virgin Megastores will give their proceeds to the Band Aid Trust charity, while Chancellor Gordon Brown has decided not to charge VAT.
