The Universe of Discourse

One song to the tune of another

I just randomly happened upon this recording of Pippa Evans singing “How Much is that Doggie in the Window” to the tune of “Cabaret”, and this reminded me of something I was surprised I hadn't mentioned before.

In the 1939 MGM production of The Wizard of Oz, there is a brief musical number, The Lollipop Guild, that has the same music as the refrain of Money, also from Cabaret. I am not aware of anyone else who has noticed this.

One has the lyrics “money makes the world go around” and the other has “We represent the lollipop guild”. And the two songs not only have the same rhythm, but the same melody and both are accompanied by the same twitchy, mechanical dance, performed by three creepy Munchkins in one case and by creepy Liza Minelli and Joel Grey in the other.

Surely the writers of Cabaret didn't do this on purpose? Did they? While it seems plausible that they might have forgotten the “Lollipop Guild” bit, I think it's impossible that they could both have missed it completely; they would have been 11 and 12 years old when The Wizard of Oz was first released.

(Now I want to recast The Wizard of Oz with Minelli as Dorothy and Grey as the Wizard. Bonus trivia, Liza Minelli is Judy Garland's daughter. Bonus bonus trivia, Joel Grey originated the role of the Wizard in the stage production of Wicked).

Yet another software archaeology failure

I have this nice little utility program called menupick. It's a filter that reads a list of items on standard input, prompts the user to select one or more of them, then prints the selected items on standard output. So for example:

    emacs $(ls *.blog | menupick)

displays a list of those files and a prompt:

      0.   Rocketeer.blog
      1.   Watchmen.blog
      2.   death-of-stalin.blog
      3.   old-ladies.blog
      4.   self-esteem.blog
      >

Then I can type 1 2 4 to select items 1, 2, and 4, or 1-4 !3 (“1 through 4, but not 3”) similarly. It has some other features I use less commonly. It's a useful component in other commands, such as this oneliner git-addq that I use every day:

    git add $(git dirtyfiles "$@" | menupick -1)

(The -1 means that if the standard input contains only a single item, just select it without issuing a prompt.)

The interactive prompting runs in a loop, so that if the menu is long I can browse it a page at a time, adding items, or maybe removing items that I have added before, adjusting the selection until I have what I want. Then entering a blank line terminates the interaction. This is useful when I want to ponder the choices, but for some of the most common use cases I wanted a way to tell menupick “I am only going to select a single item, so don't loop the interaction”. I have wanted that for a long time but never got around to implementing it until this week. I added a -s flag which tells it to terminate the interaction instantly, once a single item has been selected.

I modified the copy in $HOME/bin/menupick, got it working the way I wanted, then copied the modified code to my utils git repository to commit and push the changes. And I got a very sad diff, shown here only in part:

I had already implemented almost the exact same feature, called it -q, and completely forgotten to use it, completely failed to install it, and then added the new -s feature to the old version of the program 18 months later.

(Now I'm asking myself: how could I avoid this in the future? And the clear answer is: many people have a program that downloads and installs their utiities and configuration from a central repository, and why don't I have one of those myself? Double oops.)
