Welcome to my section of songs to use
as medical mnemonics. My disclaimer through all of this is that, although
I've worked on the songs and tried to revise them to ensure correctness,
you'll need to check things out to make sure that everything adds up (some
of the songs are lyric-heavy and info-heavy).
As for the meter - I did my best. You have to be flexible in reading some of the song lyrics - I add/repeat verses to allow room for the info.
