"Upstairs in a Tent" conjours up allsorts for me :)

For me, terrier, it conjured up a notion that had no connection with Irish bands.
In Oz, there are several phrases that start off "As useless as ..." Sometimes, for ironic effect, they're rephrased as "As useful as ..."
One of them is "... a two storied tent."
Another is "... a plough upstairs."
And a third is "... teats on a bull."
