Morrissey's twattishnessis as great as his music. The Smiths are one of the most important and influential bands in late 20C music. You'll not find a critic or serious music fan who would argue differently, even if his music is not to their personal taste. Am truly amazed people haven't heard of him.
They summed up an era, gave focus to a generation when things were really shit under Thatcher for ordinary people. For fans, their music transports you back to your youth, a time when everything was so bleak and yet so intense and unhappily wonderful all at once. They sum up the frustration, the loneliness, the paradoxically egotistical self-loathing, the grubbiness, the feelings of being limited and wanting to break out of your crappy little hometown you felt as a teen or young person. At his solo concerts now, grown men with high-powered careers storm the stage to grab him, kiss his hand, sobbing deliriously as they have to be pulled off by security. I mean, that's daft, but it's an example of how important he is, culturally. For many fans, The Smiths are a form of religion.
How anyone could her the lyrics of This Charming Man, for example, and not be moved, is beyond me (a huge fan. Although not the OTT kind!).
BTW, Johnny Marr is how you say "I'm fed up" phonetically in French, trivia fans!
