Everyone interprets lyrics different I suppose. For example they have a song Uninvited Guest:
You may not recall the moment that you asked me
But your invitation was clear
You'll pretend you've never met me but it's far to late
Now I'm here
Cause I'm the one who knows what scares you
I'm the one who loves you best
I'm the thirteenth at the table
I'm the uninvited guest
I'm the Banquo at your banquet
I'm the cuckoo in your nest
I'm your fifteen-stone first-footer
I'm the uninvited guest
I was there when you said insincere "I love you's"
To a woman who wasn't your wife
And I fronted you the money
That you ran away and blew
On the biggest regret of your life
Cause I'm the one who knows what scares you
I'm the who loves you best
I'm the thirteenth at the table
I'm the uninvited guest
I'm the Banquo at your banquet
I'm the cuckoo in your nest
I'm your New Year's resolution
I'm the uninvited guest
I'm the face you hoped you'd never see
But always knew you would
I'm the one thing you knew you shouldn't do
But did because you could
I would have sworn those lyrics were a play on words regarding 'conscience'. Mthead said nooo it's about the banished ex front man Fish ... turns out we were both wrong it's about AIDS
Shall we just call it artistic licence?
