A very strange discography as it looks that all of their first 3 album were released in the same yaer even if in different countries, so I'd say at least one was for sure recorded before

Yeah, and there’s a song on The Last Word that sounds like it might have been destined for fhat suite on the first Tucky Buzzard album as it is an acoustic transition piece with a bit of orchestration at the end.
I agree Stuart that “Warm Slash” is merely competent rock, but I think the next two albums are more memorable overall. I do like the slide guitar on “Warm Slash” snd some of the songs rock convincingly. The US-only “Tucky Buzzard” is a better album, and longer than “Coming On Again” so maybe their most satisfying record overall. But something about the gloomy orchestrated rock on “Coming On Again” stands out to me. I found a Brazilian copy and was very happy when I got to hear the vinyl! It arrived with a sticker saying “Raro!” which I’m guessing is “rare!”😀
