Cos those that you invented won’t really screw you...

To tell the truth there’s worse than that
In Hell they use the cursed B flat
Where that Devil’s chord E flat really threw you
Plus C thirteenth, F dim seventh
A minor ninth, F major eleventh
But ‘J sharp twelve of never won't’ really screw you...

Now you raised the pitch to a better key
Youve made the switch with no F in C
Even though that little B once nearly skew you
But here’s the hitch, G fourth, A fifth
B minor, then you start to twitch
Here comes an F sharp bitch to really screw you...
