Spoken: Hello, children. It's time for an important lesson with Professor Flans. This is
four letters that people sometimes confuse for one: L M N O!

[I play this on the keyboard, so here are the tabs notes and the actual notes]

The notes for the "ohhhhhhh... L M N O" part are like this:

D (xx0232@1)name="chord_133211@1">F G (320003@1)name="chord_x02220@1">A G (320003@1)name="chord_133211@1">F D (xx0232@1)name="chord_133211@1">F G (320003@1)name="chord_133211@1">F D (xx0232@1) 4x

Then back to the first thing and then the second thing and then the third thing and then 
first thing! Do it on the keyboard if you can.
