The Smiths and Blur producer Stephen Street talks Hackney, Morrissey and guitar music’s ‘last hurrah’ - The Hackney Gazette.
By Sam Gelder.

"He hasn’t spoken to Morrissey for “four or five years”, since they met-up during the re-mastering of Viva Hate. Street was surprised to see him endorsing Brexit and Nigel Farage in recent interviews.

“I must admit I’m a little bit shocked by some of the things he’s said,” Street continued. “It could be for shock value – he did like a headline or two. It could be down to the fact he doesn’t spend much time in this country and he’s a bit out of touch with the general feeling."

Street discusses aspects of working with The Smiths & Blur.
UPDATE July 31: From Alain's Facebook:

6 months before I joined Morrissey I would see the poster for Our Frank everywhere. I walked in a pub or in a restaurant I would hear Suedehead. Turn on the radio Our Frank. I loved this song mainly because of the outro lyrics. Somebody please stop me from thinking all the time. I went to a careers office they asked me what I wanted to be. I said I want to be a rock star, well of course the guy said I can't help with that i.e. dream on pal. Quite rightly so. I was tired of dead end hard working jobs. All the careers opportunities office could help me with is cleaning up Wembley Stadium. I was depressed out of my mind. I couldn't drink my pain or drug my pain away thankfully I'm not like that. I wished I didn't think so deeply but I do and that song epitomized exactly how I felt about life. Why can't I be shallow. I went for a walk in a really off the beaten park, on the ground below me someone had written out Morrissey set in concrete....

Excerpt (Google Translate to English):

As a musician against the Brexit
Speaking of beer, the title song "The Age of Boom" tells of a retired babyboomer sitting all day in the pub doing little else than explaining the world to the others. Boorer himself is not ready for anything like this. After 30 years, both daughters are finally out of the house, "more time is left for gigs". Even if the sleeping on the bus does not seem to be glamorous and he finds traveling increasingly cumbersome. In the spring, he was with Morrissey in the US. His voice stimulus was not serious, but was due to a sand storm at a concert in Mexico. "We were still wondering why the singer had a mask like a Japanese...
Blurb..."Have not played this song since I tracked it in the studio. Here's a snippet but maybe when I finally crawl out of my rock and go solo, I'll play this song. Bring out the lads."
