Living in Fame des Clash

Quelqu'un pourrais m'éclairer sur la signification de cette chanson?

So you've got to live up to your name
Or else i'll put you to shame... listen!

If you say you a selector
You a fe have good selection
A-and i say if you say you a de special
Man i say i want to know your potential

You a say you a madness
You a say you a de best
But when i put you 'pon you feet
A-some a-some a say you can't play de beat

And i hear you say a clash a you ruler
Say a clash sound cooler, eh!
Say a clash sound sweeter
And now-a-days man a measure mile in a metre, eh!

Live up to your name
Or else you die in shame
A-and a so me say fe live up to your name
A so me tell you say you die in shame

etc...
