There's a brand new Mrs Brown's Boys tonight, but with a difference, in that it's completely live. Yep. So who knows WHAT will go down with this lot. The special will see Agnes discovering that Mark and Betty are experiencing problems in the bedroom and in typical Agnes style, she takes it upon herself to fix the situation. Elsewhere, as Dermot's business goes from strength to strength, he faces a difficult decision regarding his best mate Buster. As we said though, it's live, so pretty much ANYTHING could happen. God speed, Brendan O'Carroll.
