Cover art for The Last Beat Of My Heart lyrics by Siouxsie and the Banshees

I think Siouxsie and Severin did write this song together at a time when the band was close to falling apart. According to Budgie: "it was a sad, intense expression of how far you would go for somebody". I saw them play this song in 1991 and it was chilling.

@lokithecat are you sure this is true? the band broke up 7 years after this song came out
