Whatsonstage.com has posted a 20 question interview with Peter Davison, who is seen below in his role as King Arthur in Spamalot. Davison had the following to say about his time with Doctor Who.
You're quite well known to many as being the fifth incarnation of Doctor Who. Does it all seem so long ago?
Not really, no. You're always connected with Doctor Who in some shape or form. I still do the occasional audio CD, and I'm always being asked to come in and do commentaries on the re-releases of the episodes that I did. You're always connected to it. The people who are making it now are fans of the shows from when I used to be in it, and I know quite a few of them personally.
