Kodak advert for CONCERT FOR BANGLADESH film. Click to see enlargement


Dear Thomas,

This isn't a very useful contribution but I saw "THE CONCERT FOR BANGLADESH" on it's original West End showing in 70mm. The picture quality was what you'd expect from 16mm of the time (pre Super 16 which is much better) but it was terrific because the sound made for a concert experience. The cinema, The Rialto, wasn't very big and has long since been converted into a restaurant and then shops.

Best wishes,
Malcolm Blackmoor, UK


Hi Thomas,

My Father was Chief Projectionst at the Rialto Cinema in Coventry Street. He screened the film in 35mm 4-track magnetic stereo (I did see it). I once heard that a 70mm 6-Track print screened for 3 day's at the Casino Cinema in Old Compton Street, it was taken off due to many complaints re the picture quality.

Best Regards,

"The Concert of Bangladesh" was shown in 35mm at the Hamburg Esplanade Filmtheater, there is no hint "70mm" in it. German advert from Gerhard Witte's collection


Dear Thomas,

I've only just seen that a reply has been posted contradicting my thought that I saw this in 70mm at The Rialto. The answer has to be correct but what convinced me was that there was a 70mm print credit on the end. This misleading shot was obviously also on the 35mm version. Sorry to post wrong information.

Best wishes,
Malcolm Blackmoor, UK


I ran "Concert For Bangladesh" in 35mm optical and 70mm. The 70 mm were a little grainy, to be expected with lighting levels. The surround circuit was used mostly for applause. Owing to the 70mm optics, I liked the 70mm image...I was able to run the same reel on 2 machines in 70mm on #1 and 35mm on #2....this was for my own study. The sound was excellent.
