A rockabilly movie that ends with bloopers

Can someone, pretty please, help me to identify the movie of my childhood?
I have a memory of one great movie I really liked when I was a kid (during the 90s). Unfortunately, I have never again bumped into it, so till this day I have now idea what film was it.
I don't remember much of it; I would say it was filmed during the 70s or 80s, but don't know for sure. I think it was kind of those rockabilly movies, there were some cars and some dancing involved. The main character is a young man, I even think he is an outsider and gets in conflict with some popular clique. I remember that one girl gets her hair on fire (no idea how).
Anyway, what I do remember are bloopers after the end. It was the first time I saw bloopers and I'm guessing that is why I liked the movie so much. The scene I particularly remember from bloopers is when the main character is sitting on the car hood holding pack of cigarettes. He takes one cigarette and throws it in the air, toward his mouth, and is supposed to catch it with his lips. But he fails. And fails again. And again. Finally, he manages to do that, so he takes a lighter from the pockets and tries to light it, but it doesn't work. He smiles and says something like: "It's hard to be cool".
So, if anyone has an idea what movie is that, I would really appreciate the information. Thank you
