Here’s an idea:

@uncalled4 Listening to the Beatles Channel on Sirius XM I once heard a song that started out just exactly like “Rocky Raccoon” from The Beatles Anthology III; however, it kept going after the point at which the Beatles Anthology track ends! I don’t remember exactly how it went, but the gist of it as best I remember was that Rocky fully recovered and took up with another woman who stayed true to him.

As for it not being much of a story to tell, that’s where the creativity of the script writer comes in. Take Scary Stories to Tell in the Dark. You would know if you’d read the book that a strict literal interpretation would do better as a series of shorts than as a full length movie, but the script writer took creative license to make up a main plot that connected several stories from the book. I enjoyed it a lot, and the movie sold well and got decent reviews.

Now “Rocky Raccoon” is just one story, but the potential movie could include lots of other scenes and details that weren’t in the song but that make the story more interesting and maybe even make it make more sense or give it a deeper or funnier meaning.

@Theyitis That story is better as interesting-sounding lyrics with witty turns of phrase. It's arguably like a thousand other westerns. That was Paul at the height of his lyrical powers. But great lyrics do not necessarily a compelling story make.
