(Everyone is in the great hall waiting for the concert to start. Ron, Harry, and some self-playing instrument walk on to stage. Ron grabs the microphone and turns it on. Harry checks for the last time to see if his guitar is tuned.)
Ron: Testing, testing 1 2 3. Good it works. I want to dedicate my next song to a pretty little brain in the front row, Hermione Granger.
(Hermione, ignoring his 'brain' comment, began to blush a deep red.)
Ron: Hit it Harry!
(Harry, unemotionally begins to strum the guitar as the other instruments start playing)
Ron:
I used to love her, but I had to kill her.
(At the word 'kill' Hermione's face became redder, and it wasn't because she was blushing)
I used to love her, but I had to kill her.
I had to put her six feet under, and I can still hear her complain.
(Hermione rushed to find her wand)
I used to love her, but I had to kill her.
I used to love her, but I had to kill her.
I knew I'd miss her, so I had to keep her.
She's buried right in my back yard. Yeah.
(Hermione chased Ron off stage shooting blue fire and avada kadavra's at him. They each narrowly miss Ron, as he and Hermione run up the steps of a tower, Ron's microphone still at hand. Finally Ron is cornered by Hermione and stands on the rail of the balcony. Hermione slowly walks up to him, pointing her wand at him. Before she could do anything, Ron jumps off and continues singing. And while all this is happening Harry is still strumming his guitar with the other instruments, on beat with Ron's singing.)
I used to love her, but I had to kill her.
(Ron is caught by the octopus in the lake.)
I used to love her, but I had to kill her.
She b**** so much, she drove me nuts.
And now I'm happier this way.
(Ron runs back to the Great Hall and slides on stage where Harry is still unemotionally strumming his guitar. Hermione runs down the tower and catches up to him.)
I used to love her, but I had to kill her.
I used to love her, but I had to kill her.
I had to put her six feet under, and I can still hear her complain.
(And as Ron finished his song, the last person Ron or Hermione wanted to see showed up, angrier than ever.)
Professor McGonagall: Miss Granger, Mr. Wealsey, detention, both of you!
(They sigh as the crowd carries Harry away. The crowd applauded his outstanding performance. He smiles and waves at everyone and is carried out of the Great Hall.)
