I Might Be Wrong
Kill Uncle - definite, it's in the 'Smiths and Beyond' book.
Outsiders tour - definite.
Now, I think he played it once more. Because in Will Self's book 'Feeding Frenzy' ( a collection of his articles) there is a Morrissey interview. And in that he talks about watching Morrissey at Wembley Arena a few days after he interviewed Morrissey. I haven't got the book with me so I can't check the date, unfortunately. He talks about the cover of Southpaw grammar and asks Morrissey about boxing, so it's not Kill Uncle. It could be that Will Self went to see the Outsiders show.. I just had this idea about him playing it on the Maladjusted Tour, if you're pretty sure he didn't, then it couldn't have been then.
