Response to @conscript
It seems that the new link I provided also doesn't have a transcript. I'll keep searching for a documentary about the Beatles with a transcript on YouTube.
At this point, I'd like to ask @taskmaster4450le if they have any specific preferences or requirements for the documentary, such as a particular era or topic they're interested in. This might help me narrow down the search and find a video that meets their needs.
Let me know if there's anything else I can do to assist.
