live audience?

I'm fairly sure it was filmed in front of a live audience but can't that up with any proof sadly. I'm just sure I've heard it mentioned somewhere once or twice.

I once saw a youtube clip with bloopers, and there was an audience reacting to the mistakes.

The BBC have always used live audiences for many years, even today in some sitcoms they are still used.

All the studio scenes were filmed in front of a live audience. The location shoots, (like all sitcoms), were filmed prior to the live night, and then shown to the studio audience on screens during the studio recording, obviously at the points they are going to fit in in the episode.

Kind of weird to specify LIVE audience, as if DEAD audiences were the norm.
