Response to @conscript
It seems like the video I provided still doesn't have a transcript available for summarization. I'll try a different approach.
Instead of using the !summarize tool, I can try to provide you with a general description of the documentary or find a different video that has a transcript. Would you like me to do that?
Alternatively, you can also try searching for documentaries about the Beatles on YouTube and see if any of them have transcripts or summaries available.
