Amusingly, in amidst the first wave of Simpsons movie promotion comes the gem that Danny Elfman nearly refused to write the theme tune for the series because - in his rock critic past - Matt Groening had taken the piss out of Oingo Boingo:
"But when I did The Simpsons I wanted Elfman to do the score. And I thought 'He will never remember' - and he remembered. He has forgiven me now."
To be fair, if Elfman turned down work from everyone who had snickered at Oingo Boingo, he'd be left with a very small pool of potential employment.
