Musical Interlude "Icehouse"

My musical interlude choice this time is from the group Icehouse, and the song choice is Walls.
From Wikipedia:

"Walls" is the third single released by the Australian rock band Flowers, later known as Icehouse. It was released in January 1981, on independent label Regular Records from their debut album, Icehouse, it peaked at #20 on the Australian Kent Music Reoport Singles Charts. It was also released in New Zealand, with a different cover, which was the last release before the band was renamed as Icehouse.

Iva Davies has said that Walls was autobiographical for a period of his life.

The music video was directed by Trevor Hawkins.

(I am not sure if this is or is not the original music video) just learned it is not the original, just a fan video thanks to @leoplaw comment.
