Disclaimer: I don't own this play Starkid does and I don't own Harry Potter, if I did Severus would be mine!
Harry Potter was sitting in his room working diligently on his potions homework when a flash of light surprised him. He turned to see what it was and saw an inconspicuous envelope sitting on his bed. He picked it up and took out a letter that read,
Harry,
My name is Anastasia, and I am from the future. I have come across a musical that I wish for you and certain others to see. The others are Hermione Granger, Ron Weasley, Ginny Weasley, Fred and George Weasley, Sirius Black, Remus Lupin, Albus Dumbledore, Severus Snape, Draco Malfoy, Lucius Malfoy, and Tom Riddle. I will be there as well and will make sure that no harm will come to ANYONE. If you agree to go then take the coin out of the envelope and say "Musical".
Harry raised an eyebrow and shook out the coin before saying musical. He felt the telltale feeling of portkey travel and landed with a thump on someone's chest.
"Potter, will you please get off of me?" A smooth voice slid over him like silk on bare skin. He jumped up and saw a seventeen year old Tom Riddle looking up at him amusedly. Harry blushed and managed to stutter out a quick apology before he was wrapped up into a pair of arms, and he could tell by the brown bushy hair that it was his dearest female friend, Hermione Granger.
"Hey Mya. How has your summer been?" He asked whilst smiling up at her. It was times like this that he was internally cursing his height, or lack thereof.
"It's been good midget. The others are all here so let's go get ourselves seated in the living room." Hermione said before leading them all from the entryway to the living room.
They all sat down on the numerous couches in the order of: Severus, Harry, Tom, Lucius, Draco, Hermione, Sirius, Remus, Fred, George, Dumbledore(I don't like him so he will henceforth be referred to by his last name), Ginny, Ron.
In a flash of light I appeared and clapped my hands startling Harry from his silent wondering about where he had been pushed to sit. "So you all are going to be watching a set of video called A Very Potter Musical by Starkid!" And with that I started the playlist on the television and disappeared.
