I do remember McKeever simply cos UTV original shows were all factual, e.g. Kelly, Lesser Spotted Ulster, School Around the Corner, Jenny Bristow and All Mixed Up, and it was a rare comedy effort. Didn't she also do a series of ads in various roles, possibly for Abbey national... IIRC she dragged up in stubble.
I loved Give My Head Peace as a kid not having a clue what it was actually about, though I am a Protestant educated Catholic. Half the non-Hole in the Wall cast have been in Game of Thrones.
THITW Gang's other stuff though, didn't they try drama, some Fr. Brendan Smyth biopic with future GOT actor Ian Beattie as the bumming bastard. Seeing him as Meryn Trant was a cultureshock, knowing him only as evil priests, i.e. his role in RTE sitcom Killikaskully, a sort of lighter League of Gents via Fr. Ted with that series' Pat "Tom" Shortt as various characters.
