Surely that must be the most shitest job in the whole world...?
Imagine that you wanted to be a musician and studied all your feckin life to play the violin or cello or whatnot...
...and you are brilliant and your fingers are fucked and you spend your whole life lugging around your instrument of choice on the tube and stuff...
But you spend your whole career backing up some other fucker that is no more talented than you but for whatever reason got the break....
...and he sits at the front and gets the applause (and the cash)...
...and you sit at the back and think how much better than him you are but politely tap your bow on the strings at the end of the concert...
...and you know this is as good as it gets...
