Christopher Frayling interview RE The Battle of Stalingrad

I recall seeing a interview (video) with Sir Christopher Frayling where he describes in vivid detail what would be the opening sequence to Leone’s The Battle of Stalingrad. But can’t for the life of me remember where it was from.

Does anyone else remember this interview and can point me in the direction of where it was from, perhaps a YouTube video?

Thanks!

Remember the interview yes. Something he did for the BBC or Channel 4 in the U.K. Wonder if it is the 1989 documentary for the BBC called Viva Leone…
