[after you]

Just after the new album’s release in December 1973, Diana told Paul Gambaccini in Rolling Stone: “I’ve loved Marvin for years and wanted to record with him. We did a great number of songs together during the last year and a half, so many that I didn’t know which ones would be selected for the album. As a matter of fact, I didn’t know which one was the single until you told me.”

Interesting that the article finally gives a date for the recording of "I'll Keep My Light in My Window." -- 1978.

The recording date has been the topic of much speculation, so nice to have it confirmed.
I certainly consider the song commercial enough to have been released as a single in 78. Perhaps more so then “Lovin, Livin & Givin”. It would also have made a welcome edition to Ross 78.
