As with the others, sing it to the Blackadder closing theme tune!
Harry Potter and the Half-Blood Prince Song
The year's events were set in motion
Malfoy undertook a cunning plan
Harry actually made a good potion
and said that he was Dumbledore's man

Oh Serverus! Oh Serverus!
You were really the prince
Oh Serverus! Oh Serverus!
That sure made Harry wince!

Oh Harry! Oh Harry!
What about R.A.B?
Oh Harry! Oh Harry!
Important don't you see?


You can expect the 7th song sometime after book7 is published!
