Brilliant song. Isn't it about a nightlight? Quite abstract of course.
There's a picture opposite me
Of my primitive ancestry
Which stood on rocky shores and kept the beaches shipwreck free
- Nightlight imagining of its ancestral Lighthouse
And it would be fired if it tried to be a lighthouse as it is only a nightlight and thus its light would be too weak to divert the Argonauts away from the rocks.
Blue canary in the outlet by the lightswitch
Who watches over you
I'm your only friend
I'm not your only friend,
but I'm a little glowing friend,
but really I'm not actually your friend; but I am
- The nightlight itself
