Do anyone has more information about these theories who said K-on is based on 5 girls who died on a plane crashing??
If it were true, it would be the first time that K-On! gets within the same galaxy as entertainment and not just be a black hole of boringness so I can see the appeal behind the concept.
It's also based on SRV, Ritchie Valens and Buddy Holly
So Yui is Dr Pavel, Azusa is CIA, Ritsu is Masketta Man, Nodoka and Sawako are two random soldiers who are seen on the ground before the plane takes off and Mugi is the Big Guy himself.
