Lyric discussion by JhonnBalance 

Cover art for Push the Sky Away lyrics by Nick Cave and the Bad Seeds

This song is a direct answer to one by COIL in 2004 titled "Heaven's Blade." Nick Cave followed the musical output of the seminal electronica & dark-wave pioneers COIL (post-Throbbing Gristle & post-Psychic TV), having had acquaintances with founding members Peter "Sleazy" Christopherson & John Balance (a/k/a Geoff Rushton) since way back in his Birthday Party London days. This correspondence would confirm the interpretation offered by previous commenters. Be Here Now = Now/Here Be.

My Interpretation

@JhonnBalance enjoyed seeing Peter Christopherson in the recent Squaring the Circle documentary on Hipgnosis. Currently on Netflix UK.
