you know, that thing from the producers of 'Metal:A Headbangers Journey', 'Iron Maiden:Flight 666' and 'Rush:Beyond the Lighted Stage'
I say sort of invited because it was more of a "I was going to invite you actually but it’s about metal music and so you’d probably hate it and a travel card is like £8 now." which is true but whatever.
There is suggestion on the invitation of very metal sounding cocktails and canapés after the screening though. Or at least typed in a font which tries to make it look less poncy and more \m/.
