In fairness, the duo did lighten their tone a little before disbanding in 2006, but Moffat's lyrical themes were not to be compromised, effectively casting Arab Strap as the archetypal Scottish miserablists.
Philophobia's opening lyric is as follows:
"It was the biggest ever cock you'd ever seen,
but you've no idea where that cock has been.
You said you were careful
you never were with me.
I heard you did it four times
and jonnies come in packs of three."
You get the picture.
