The 1979 movie Rock 'N' Roll High School features the punk band The Ramones.
The Ramones all have prominent cameo roles in the movie where they are all named and several of their actual albums are referenced.
Although the members of the band all have the same surname, they are NOT brothers, nor are they related in any way. The surname Ramone was adopted for entertainment purposes only.
There is a scene in the movie where Riff Randell claims that she would love to be the only sister in their family.
Riff: Kate, do you realize that they're all really brothers? I mean, imagine being the only sister in the Ramones family!
What was the purpose of including this in the movie? Is there any evidence that the band requested that this be added to the movie?
