Has John got a brother or a sister ?

I've never heard about it...maybe someone here now the truth... thank you for advance :)

Isn't he related to David Hasslehoff?

lol, maybe with the curly hair...or the voice loool

Lol, never thought about the voice. :-p

he has a sis, i believe

i think Freddie and Roger were the only Queenies who had a sister

I could have sworn John had a sister too cause she was quiet and shy like him.

David Hasslehoff? John?
Hmmmm sings I been looking for freeeeeeeeeedom!

No you divvies he's the brother of K.I.T.T I know this David Hasslehoff thing but its just chinese whispers he's actually got a Trans-Am for a sibling.

To answer the question: John has a sister called Julie, born in 1956.

What YV said.

I thought John was an only child, since his father died when he (John) was 10

Dark, by your logic, that measn that John's siblings would have absolutely had to be 10 or more years younger than him.

If you do the math,
John's dad prolly died around 1960 or 61. Julie was born in 56 so yes John did had a sibling.
