Keep It Up Network?

Apparently ‘Keep It Up Downstairs’ is among the 450 films in this deal, rumour is that Network will be releasing it on DVD next may.

That would leave Private Pleasures, Whats Up Superdoc and Erotic Inferno, as the only Mary Millington feature films yet to be given a legit DVD release. Keep It Up Downstairs hasn’t been seen in the UK since a VHS release in the 1990s and several (heavily cut) TV screenings on the Beep towards the end of that decade.
