Jarvis and co had finished their A levels and left City School but came back to play with the Electric Armpits. The concert was videoed (!) and I remember Jarvis returning again to see the screening. Sadly the video was loaned to a member of the Armpits whose parents taped Corrie over it.
Also playing were In A Bell Jar.
The singer of the Electric Armpits wrote a book about the times with many references to Jarvis: http://ebookwyrm.blogspot.co.uk/2012/12/the-armpits-are-electric-by-ian-turner.html
