Yep, that's right, it's completely live. The show usually leaves in the bloopers that others take out anyway, but we can imagine there's going to be more than a few incidents of corpsing, stumbles and fluffed lines.
It's a one-off special, all part of the Beeb's sitcom celebration season, and Agnes Brown will be giving us her unique brand of comedy, no holds barred.
The show started off in the theatre, so we're expecting good things from the talented cast.
Mrs Brown's Boys Live, BBC1, 9.45pm
