The bass line was originally part of the synth-guitar. At someone else's suggestion I pulled it out, took it down an octave and set the instrument as electric bass. I then extended it 'forward' to give the first complete refrain. Apart from that, there was just some re-balancing and tidying up.

This is exactly what I wanted to achieve! A light fun tune. Now all I need to to is decide what nationality 'Trixie' is
I think she's too bright and lively to be English
