Give It A Rest!

If you haven't noticed yet, my mind tends to wander off into some strange places. For instance, Bob Denver's death caused me to reflect on Gilligan's Island .
Specifically, the show's theme song. Remember? With Gilligan, The Skipper Too, A Millionaire and his Wife, A Movie Star, The Professor and Mary Ann...Here on Gilligan's Isle!
But remember? There was a second version. With Gilligan, The Skipper Too, A Millionaire and his Wife, A Movie Star and the Rest...Here on Gilligan's Isle!
And the rest?
Was the entire show not cast when the song was written? Was it writer's block? Or is simply that strange thing that happens to me once in a while when someone says hello and try as I may, I can't remember their name?
And the rest? There were only two of them. The Professor and Mary Ann, the epitome of midwest wholesomeness and crush object of young boys everywhere. Mary Ann, I mean.
What if this applied to other songs?
Are you going to Scarborough Faire...Parsley, Sage and the other spices
...And on this farm he had a pig...Ee-I-Ee-I-Oh...With an oink oink here, etcetera etcetera .
Ain't No Sunshine When She's Gone and She's Always Gone Too Long, Everytime She Goes Away and I Know...I Know...I Know...I Know...I Know...blah blah blah
I could go on, but you know the rest.
