Write really overly-funny super hilarious comedy 17+ short Scooby-Doo  parody transcript based on my prompt: (but make it more funnier adult comedy where the gang constantly make fun of the plot and roast the villain's costume choice, and roasting the monsters names and peoples names and point out inaccuracies in locations and motives), 

The gang headed to the Coolsville Amphitheater, to see a Buddy Chilner concert. To get the best seats, Daphne bought all the tickets, which cost $27,345.89. Right before Buddy could begin his song, a ghost shows up from the darkness and grabs Buddy.

The gang then makes a run for it, but Daphne and Scooby refuse to leave without Buddy. After saving Buddy, the ghost then steals the money from the ticket booth and disappears. Buddy explains that was the ghost of Purvis Parker, who was the dude of rock 'n' roll and Buddy's idol. Rumor has it, he disappeared years ago. Recently, his ghost has been showing up at all of Buddy's concerts. After Buddy hires the gang, they see an old man leaving the Amphitheater. Buddy says he's a fan who comes to all his concerts. The gang go to ask the man some questions, but he has already left. Scooby takes a picture of a pizza parlor that the car was passing, but with Velma's magnifying glass, the car's bumper sticker reads, "When in Coolsville visit Parker Place Home of the Dude of Rock & Roll". Buddy says that's where Purvis lives, so the gang decided to head there.

They meet the caretaker of Parker Place, Mr. Dilton, who explains that after Buddy became famous, everyone stopped coming to Parker Place. He charged the kids $2 a piece, which Daphne paid for with a $100 bill (her smallest bill), but Mr. Dilton has plenty of change, which Velma finds suspicious.

Upon entering the house, the gang splits-up to look for clues, but find nothing. They hear guitar music from the recording studio with someone inside. They find a man, who introduces himself as Lenny Lipner, a Purvis impersonator. He blames Buddy for making people forget all about Purvis. He claims he doesn't know anything about the ghost, and rudely forces them to leave. Scooby's nose then detects a clue, with the gang in pursuit. Scooby leads them to Purvis Parker's secret vault, and upon looking inside, they find fake gold records. Suddenly, the ghost shows up and grabs Buddy again.

As the ghost closes in on the gang, Scooby hides in the ceiling light, which causes the roof to give way, trapping the ghost. The gang and Buddy climbs the debris to the next floor. After escaping the ghost, Velma finds tanks of compressed air where Scooby was hiding. However, the ghost appears from the window and finally escapes with Buddy, which provoked Daphne and Scooby.

While looking outside, they see the old man from before, and thinking he's the ghost, go after him But they catch Mr. Dilton by the pool, instead. Angered, Mr. Dilton decides to close down Parker Place the next day. After he leaves, Scooby coughs up Buddy's guitar pick. The ghost emerges from the pool and pursues the gang.

And after a long chase they finally lost him. Not long after, Velma solves the mystery and comes up with a plan.

Back at the Amphitheater, the gang finds Purvis's gold records hidden backstage, when the ghost appears and pursues them again. Daphne hopes Scooby remembers what to do when they say "now." Scooby, however, reacts at that moment and cuts the rope, which triggers the trap and catches the gang by accident. The ghost chases Scooby into a corner, but Scooby grabs a nearby guitar and turns the music up way too loud, and after a few strums, the ghost crashes into the drums. After freeing the gang, they went through the suspects; Daphne thinks it to the old man they saw sneaking around, while Shaggy and Scooby believes it to be Lenny Lipner. But Velma unmasks the ghost as Mr. Dilton. She first suspected him when he made change to Daphne's $100 bill, even though business was bad at Parker Place, and she knew he must've dropped Buddy's guitar pick in the pool. He was the one stealing Buddy's concert money, and he also stole all of Purvis's gold records. He also used the compressed air Scooby found hidden in the ghost's jacket to fly. Buddy emerges with the concert money along with the old man, who Velma says is the real Purvis Parker, much to the gang's surprise. Purvis explains that he wanted a little peace and quiet. And since he's a big fan of Buddy's, he never missed one of his concerts, and after the ghost appeared at the last concert, he followed it back to Parker Place. Mr. Dilton curses the gang, saying that he would've ruined Buddy if it weren't for them and Purvis.

Later, the gang and everyone in Coolsville watched Buddy, Scooby and Purvis perform their new song onstage, "A Pup Named Scooby-Doo".
