The Old Asylum

An abandoned old hospital at night, drawn with code and played by your song: walk its long corridor by lantern light as doors ease open on the beat, then stand in the moonlit ward, at the nurses' station, in the records room, outside under the clock tower and in the old cage lift. Eerie and gentle: 13 and up for everyone.

The Long Corridor

The long corridor walked by lantern light: doors passing on both sides and easing open on the beat, a lamp glowing far off, fog along the floor and, on the drop, a wheelchair rolling slowly across.

Classic Studio

The Empty Ward

The empty ward under the moon: made beds in rows, the curtains between them swaying, and a sheet lifting from the far bed to drift up into the moonlight.

Classic Studio

The Nurses' Station

The nurses' station after hours: the call board lighting a room's lamp on each beat, the telephone's receiver lifting, papers rising off the counter.

Classic Studio

The Records Room

The records room: rows of filing cabinets, a drawer sliding out on each beat, and on the drop the files swirling round the room under the swinging bulb.

Classic Studio

The Building at Night

The building from the grounds at night: its windows lighting one by one with the beat, the clock tower keeping the song's time, bare trees swaying and fog on the lawn.

Classic Studio

The Old Cage Lift

The old cage lift: the scissor gate easing open on the drop, the floor dial's needle climbing and coming back down, the cables running and the bulb swinging.
