Every time I hear people say Delgado was on too often in that season I'm just shaking my head, because with his premature death it's all the Master we got to have. I'm grateful they 'overused' him while they could.

Yes, me too. Well, I have to agree that he was overused, but I'm grateful that he was overused and we have those episodes. Btw, the commentary included a lot of fond recollections of Delgado, and also of Jon Pertwee. Sad though that the next commentary will have fond recollections of Barry Letts. I don't know if this was the last commentary he did, but it must have been one of the last.

may have to rationalize buying a dvd, in spite of already owning it on vhs.

I go through that too.
