I wasn't sure it was really them until I went to the wikipedia page and saw this picture.

I've actually watched one of those pseudo-Doctor-type shows. I think it was called "Zero Imperative" or something like that. It's been a long time. But, I do remember it had Jon Pertwee, Peter Davison, Colin Baker, Sylvester McCoy, and a couple of the companions all playing different characters. Pretty fun, in a fanboy sense...
