WHO'S THAT? AN SGA IN "SJA"?

For those of you who have seen 'The Sarah Jane Adventures' presentation of "The Mark Of The Berserker" (Part Two), I'm wondering if you thought the same thing as Clyde and his Dad went on their "shopping spree".....

Up ahead of the two Langer men was a white-haired gentleman dressed in a black jacket that for alls I know could have been velvet.......

Granted, Jon Pertwee is dead in the real world. But in Toobworld, it's still possible for previous incarnations of the Doctor to be showing up in the present time between their televised adventures.

I have no clue if this was a deliberate tip of the hat cameo by an extra to the memory of Sarah Jane Smith's first Doctor. But had she been there with Clyde and Paul Langer, don't you think she might have called out "Doctor....?" upon seeing that mop of white hair?
Just sayin', is all......

BCnU!
