>>I'll bring you incense(,) owls by night

My wife sings Chelsea Morning and I have always found the above to be something of a bizarre line.

Is it a really angry owl? As in "incensed owl". Why would you give someone an angry owl?
Or is it an owl who has been perched in an incense-laden atmosphere and presumably smells pleasant as it quietly flies past you - a bit like a live air-freshener.
And even if it's not smelly or cross - why would you bring someone an owl? It's very strange behaviour

I used to reckon it was an incensed towel which might be quite pleasant.

Enjoyed your web site by the way and your descriptions of your return to singing at Cropredy were sweet, and the library experience.
