Hey guys, I've bought my ticket for H + S a long time ago for the show in Paris.
But a friend of mine would like to come too, but unfortunately the gig is sold out now... if you know anyway to sold this out I'd be glad... any website when you people sell their tickets back or if it may be possible for the evening of the gig to buy a ticket at the venue...
Thanks for reading, anyway!
