The new TV Guide article (from their soaps column) has a line about Frid still playing Barnabas 39 years after the show went off the air on the Big Finish recordings.
My guess is that this statement, which is completely untrue, came out from the reporter visiting a website and looking at the first CD, which I think did have a picture of Jonathan (as Barnabas, of course) on the cover, even though his voice did not appear on the recording.
We do live in the age of spin but implying, as the statement does, that Jonathan Frid has continued on playing Barnabas for the last 39 years is extreme, even by the standards of today.
