This has quite the lineage. Originally shot on film (most likely 16mm), it was sped up for a PAL conversion (25fps), to be shown on TV and what-not. Decades later, Queen Productions royally fucked it up (as they so often do), by converting that sped-up video to NTSC (30fps), resulting in extra frames being created, and hard to remove. Not wanting to bother undoing the PAL-to-NTSC conversion (which is hard to do right without professional equipment), I simply just slowed it down to the correct sped. Then I synchronized a much-superior audience-sourced recording to the video. TL;DR: It now runs at the correct speed, with better audio too.
