But « every third thought » sounds very Gillovny to me. Didn’t Gillian once say her favourite colour was the fade blue of the sky before dawn?

Yes, she said that once. But as long as we don’t know when David wrote his new songs, it’s hard to tell. He said he wrote many of them at the time he got divorced from Tea. So it’s possible he wrote that one at this time. It could fit too. 🤷🏽‍♀️
