From Jimmy Page's facebook :

On this day in 2020, Scarlet by The Rolling Stones, featuring me, is released.⠀
⠀
I was invited to Ronnie Woods’ house in Richmond to do a session in October 1974. It was said that Keith Richards and Ian Stuart (Stu) would be there. It sounded a good opportunity to catch up with old friends.⠀
⠀
There was Keith Richards on electric guitar, myself on electric guitar, Rick Grech on bass and a drummer and engineer I had not met before. Keith kicked it off and I began to mould a riff around his guitar part to augment the arrangement. It began to lock-in pretty soon with the musicians and we all got a successful take that evening. I’d had a good time working with Keith. ⠀
⠀
It was said they were continuing the following night at Island Number 2 Studios in London. I said I’d go and play some guitar soloing on it. I arrived early on that evening and got to do it straight away within a few takes. It sounded good to me and I left them to it.⠀
⠀
Mick made contact with me recently and I got to hear the finished version. It sounded great and really solid.⠀
⠀
I’m happy they chose to release it as part of the forthcoming Goats Head Soup 2020 album. It’s an ultra-rare appearance of me outside Led Zeppelin in the ’70s.

and a few notes from Martin Elliott's facebook page 'The Rolling Stones Sessions'

It was at this time, on 4 October 1974 that at Ron Wood's Wick home studio in London, along with Ric Grech (Traffic's bassist), Bruce Rowland (Fairport Convention's drummer), Ian Stewart and Jimmy Page, a small session evolved which worked on the song Scarlet. Jimmy worked on a riff around Keith’s guitar part. This was a Jagger, Richards song described by Jimmy that was in the mould of folk but featuring reggae style guitars. Jimmy thought it was particularly good, something you would get on Bob Dylan's BLONDE ON BLONDE album and would have made a good B-side. The following evening, Keith Richards went with Jimmy to Island Studio No. 2 for guitar overdubs and transfer from eight to 16-track. The tapes also contain a long unavailable jam with Stu, Jimmy and ‘Keef’. Soon after, the tapes were taken to Switzerland by Keith where they were listened to and Keith described the content as something from a possible Page solo album project. Scarlet Lilith Eleida was the then three years old daughter of Jimmy with his partner Charlotte Martin. In September 2020, the track became a stretched addition to a GOATS HEAD SOUP re-issue since the album had been released over a year before Scarlet was recorded. However, it was a welcome and anticipated addition which while unheard had gained some folklore credibility over the years by fans. Scarlet was given a fresh coat of paint by Mick in spring 2020 by overdubbing vocals, an acoustic guitar and some percussion.
It was released as a download on 22 July following a preview with a brief Mick and Jimmy Page interview on Zoe Ball’s BBC Radio 2 breakfast programme. The 2020 recording has a short and lively staccato guitar intro before the percussion and vocals enter. It develops into a catchy refrain followed by the first lead break from Jimmy which holds interest. However, unlike the mechanisations behind Criss Cross which integrate into the era the overlying stratosphere of Scarlet is modernistic and somewhat forced. It contains some cuts, splicing and pasting to lengthen the track as the original tape box testifies with a timing of 3.05. The tape notes state the Cockroaches as the artists which was a much-used studio anonymity tactic. Many of the bonus out-takes from the re-issue of GOATS HEAD are contemporary instrumentals and re-mixes and Scarlet may have been best served in that ilk.
