I saw it written.. the title il Chelsea Morning and it goes like this:
[...] When the curtain closes and the rainbows runs away I will bring you incense owl by night by candlelight, by jewel-light if only you will stay! Pretty baby, won’t you? Woke up, it was a Chelsea morning!
I think there could be a mistake in the original text, but I've never heard the song so I couldn't tell. I've just been asked to translate it.
