Guy has so far told us:
There's at least 1 track with Richard Bennett on mandola.
There's at least 1 track with Greg Leisz on mandolin.
Seana Davey plays the harp on 1 track.
Ed Cervenka is on cimbalom at least on 1 track.
Tamsin and Emma Topolski are backing vocalists on at least 1 track.
The sessions featured other several guest musicians, whose names Guy did not mention yet.
Apparently, the sessions started in early 2021. Then they resumed at later part of the year, which ended in November 2021.
Those 2021 sessions were mostly Guy and Mark working on demos.
February 2022 was the continuation of the sessions with the full band there, with new member Greg Leisz, who according to Guy fit so well with the band as if he was there before.
There's probably a lot more sessions in 2022 and 2023, but they're not yet documented in the studio diary, as we still wait at this moment for part 4 of the diary.
I wonder if the album (and EP) will be a mix of different sessions or if the later sessions will prevail a whole lot more.
Oh yes, Guy also said that sometimes the first takes of songs are the best and when they do more takes they actually overdo them so.. We might have some one takes ending up on the album.
