[The Soup Nazi]

I assume that what it's being referred to is Morrissey's appearance on 1992's Madstock Festival. From Wikipedia:

NME [...] accused Morrissey of racism on the basis of the imagery he employed during his 1992 performance at the Madstock festival in North London's Finsbury Park [which featured Flowered Up, Gallon Drunk, Ian Dury and The Blockheads, Morrissey and Madness]; Morrissey included images of skinhead girls as a backdrop and wrapped himself in a Union flag. Conversely, these actions resulted in him being booed offstage by a group of neo-Nazi skinheads in the audience, who believed that he was appropriating skinhead culture.

The neo-Nazis booed him for copyright infringement, priceless. Of course, nobody said dick just a few years later during the ridiculous Britpop boom, when Blur and Oasis also wrapped themselves in the Union Jack.

Back to Madness, between Viva Hate and Your Arsenal Morrissey tried to make a whole album (pieces of which ended up on Bona Drag) with their producers Clive Langer and Alan Winstanley. From Uncut:

It's hard not to see the appeal: Morrissey had long admired the Nutty Boys' eccentrically English take on ska-pop, and hoped to channel something of their style as he redefined himself as a London artist. But he also envied their audience: though Smiths gigs were notoriously rumbustious events, Morrissey was still caricatured as the stereotypical NME-reading, vegetarian, bedsit-dwelling student artist. Particularly after the break-up of the band, the loss of his "gang", and, particularly, Johnny Marr's still vital links to the Perry boy culture of Manchester (the lads who would eventually form the Oasis audience), there is a sense in which Morrissey longed to reconnect with a working-class audience — the desire which would eventually lead him to make his appearance at Madstock in 1992.

In the short term, the decision proved catastrophic. The first fruits of the collaboration with Langer/Winstanley was "Ouija Board, Ouija Board", on the face of it charming enough, suggesting Spark soundtracking a mid-period Ealing Studios confection. The timing of the release, however, ensured Morrissey was scheduled to appear on the same Top Of The Pops as both The Stone Roses and the Happy Mondays made their debuts. In this context Morrissey seemed less a venerable art-pop institution, more embarrassing old uncle. As Madchester went mad, Morrissey seemed too trad, dad.

The experience seems to have damned the collaboration before it had even begun. Which is a shame, as in retrospect it's clear it produced some of the greatest songs of his solo career. "Piccadilly Palare" is a great lost single, almost the epitaph for his failure to move to Madness-ward. Despite the Mike Barson-style piano intro, it howls into desperate life with Morrissey chronicling the fleeting, seedy glamour of early '70s rent boys. In this context, palare, the slang of the gay underworld, becomes a metaphor for Morrissey's self-perceived artistic failure to ever really cross over, to become the kind of nation's favourite that was Madness' destiny. "You wouldn't understand," he mutters. "Good sons like you never do." "No, no, no, you can't get here that way," notes guest vocalist Suggs.

"November Spawned A Monster" was even better, an extravagant homage to the New York Dolls' "Frankenstein", and, with a hysterical video shot in Death Valley, his most beautifully extreme single. Its failure to break the Top 10 seems to have been the final nail in the Langer/Winstanley coffin and so a scheduled album was redrafted as a compilation, mopping up the singles and B-sides from the early solo years. Despite its conception, Bona Drag turned out to be a superb package, highlighting the strength in depth of Stephen Street material (the inclusion of "Hairdresser On Fire", "Will Never Marry" and "Disappointed" on Viva Hate would have made an album that rivalled anything by The Smiths) and, beyond the Madchester moment, the charm and power of the Langer/Winstanley songs.

Eventually we'll get back to "Sonic Youth on bandcamp", but I had to type all that Uncut text, so if you didn't read it you suck.
