The plot and lines are very similar to a song we used to sing at college in the 1960 that we called "The Lady Mechanic" but there were a few extra lines and a different tune:

Anon.
Collected at Bowdoin College in the early 1960's

The Lady Mechanic

G
I know a lady dressed in black,
-------------------------G7
She makes her living on her back –
-------------------C
She's a lady me-chanic,
-------------------G
She's a lady me-chanic,
---------D----------------------D7------------G
She's a lady mechanic and I love her any-how.

I know a lady dressed in red,
She makes her living going from bed to bed –
She's a registered nurse…

I know a lady dressed in green,
She makes her living pounding meat lean –
She's a lady butcher…

I know a lady dressed in brown,
She makes her living going up and down –
She's an elevator operator…

I know a lady lives on a hill,
Every night she gets her fill –
She's a blueberry picker…

I'm thinking that I composed the last verse.

Cheerily,
