What do Buddy Holly, John Lennon, Jimi Hendrix, Elvis Presley have in common?

They were all painted on the side of this bus. Does anyone recognize this bus or know anything about it?  Asking for a friend.

They are all dead?

They are supposedly dead but what's the real reason why they don't let people into area 51?
Perhaps they all live there.

Looks like the bus is a Model 05 or 10 Eagle Entertainer done in the 80's, probably by one of the converters in Nashville or Memphis. My 84' Entertainer has the same pair of smaller custom windows in the rear. If the picture was clearer it might be possible to see the artist's name below the artwork to the left.
