The whole post is very much in line with the eulogy Morrissey wrote when Prince died. It was a bit unfortunate but very typical how he compared him to the Queen.
"Prince is the royal that people love, whereas Elizabeth 2 was thrust on the people who have never been asked whether or not they want her."
Personally I think it was a random find and they liked it for obvious reasons and posted it.
I suspect that Morrissey has been increasingly interested in Prince in more recent years, using his music in pre-show tapes and mentioning him on stage and on Central (he mentioned him along Bowie and the Dolls in his post on Little Richard). In the 80s he wasn't very fond of his music and said he was overrated but didn't dislike him.
"Q: What do you think of Prince? He’s a lot sexier than you . . .
M: He’s clinical and impersonal . . . but sexy? I don’t know, I don’t think so . . . On a lyrical level I don’t find him desperately interesting. His beat isn’t very good either. But I don’t dislike him, I find him quite funny and arrogant and confrontational. At the end of the day though, he’s s-l-i-g-h-t-l-y overrated."
I seem to recall more quotes, some more favourable, some rather derogatory, but can't find them right now.
It's just fair enough to change one's opinions 30 odd years later though. And maybe I'm the only one but I can hear some Prince influence on I Am Not A Dog On A Chain, so maybe there was a mention to that effect towards the musicians and Chiccarelli as well, who knows.
