The Beatles
Yoko Ono and John Lennon kept their celebrity status so far away from family life their son Sean had no idea his dad was a former member of the Beatles.
Ono has revealed she and her husband were so desperate not to force their son into music, they refused to talk about it at home - and he had to find out about his father's superstardom on his own.
Ono explains, "I was prepared that he (Sean) might become an archaeologist or something. John didn't even want to tell him that he was a Beatle. Sean found out from someone else. One day, he even asked John, 'Were you a Beatle?
"When Sean was in his twenties, I found out that he knew all of the Beatles' songs, all of John's songs and all my songs - every lyric."
