Talk In Circles - I'm The Cure

"Kilo pascals in my finger" - as the Pascal is a measure of pressure, I guess kilo pascals signifies a lot of pressure. It's possible that Moginie wrote this to suggest that the finger has the power to apply a lot of pressure - either pointing the finger (eg in a court of law) or pehaps a finger poised over "the nuclear button"??

"God is hiding in this teacup" - could this refer to people looking for divine inspiration by that ancient art of reading tea-leaves?

The actual lyric that's sung is "God is hiding in this pickup" so, referring to playing guitar, it fits perfect with the bit about "kilopascals in my finger".

'God', in the sense used by the lyricist here refers to salvation - in the form of heroin.
