John Lemon: Happy Birthday!

My son is OBSESSED with the Beatles (John Lemon, Bingo Starr, Paul, and George) and John in particular. Upon seeing the Google home page celebrating John's 70th birthday he got very upset. His questions:
Why is he dead?
Can you touch him or is there glass around him?
Is the man who killed him in jail?
Why did he kill him?
Did he use a gun?
J was so distressed that I had to change the subject. We watched lots of youtube videos, some had Julian and Sean in them and he wanted to know
Who took care of Julian when his papi died?
Poor J, his hero dead.
Thank you for the best music ever.
We love you and miss you John. Happy 70th!
