Here’s an interview with Paul Rutan Jr. who did the restoration on the AMC A Hard Day’s Night and Help! Worth a listen as its very informative as to the lengths he went to retrieve prints of these films.
The mono audio track on AHDN came from a UK print as the original US prints had the volume turned up on them encase the film couldn’t be heard over the screaming teenagers in the audience. This meant the US prints all had clipping and distortion.
I know this is an older thread, so how does the AMC soundtrack compare to the more recent Criterion version?
