Glasgow Patter: tenement life
dancer
A slang term for a landing or floor in a tenement building, e.g. a three-dancer is the third floor; a four-dancer is the fourth floor: "How is it whenever Ah've tae deliver a new machine it's always a four-dancer?"
A tap-dancer is, of course, not a variety turn in this context but the top (tap) floor.

The stone-built tenement is a major feature of Glasgow's urban landscape. Built in large numbers from the mid-1800s to the early years of the 20th century to accommodate the city's growing population, many disappeared after the war as a combined result of decay and eager urban planning. In recent years there has been a policy of sensible rehabilitation of this architectural style.
