I remember Dr Who when I was very young.Sarah Jane was an assistant of Dr Who but I can't remember which one. I'm sure someone else can. Bedtime for me. Goodnight.
Ever since she joined Dr Who I have believed her to be the niece of Stirling Moss......
I must have gleaned that bit of information from 'somewhere', but can find no reference to it.........
Have I been mad since 1973, or can someone explain why I have been believing this ?
