I think they’d do a little better than that. There seems to be a lot of nostalgia for the 80s / early 90s era these days, and Your Arsenal was a great comeback album for Morrissey.As much as I love Alain and the other ex-band members, I'd be surprised if they could pull a live audience larger than a small pub.
On a personal note, I happened to visit an exposition of photographer Chris Killip in Newcastle, which really captured the darkest side of North England in the seventies and eighties, and seeing a photo of glue- smokers, I immediately thought of Glamorous Glue and how YA would make the perfect soundtrack of this dark area. YA had this rough and dark edge to it, and many references to the working class cultures of that same period.
Maaybe there’s a lot of nostalgia in that record for Alain too.
