Last night I found a very obscured live video of Sea Girls performing at NME London on 3 May 2018. Turns out the song they played is an unreleased (also unfinished) Sea Girls song called "Stranger Things" (as Andrew told me after I asked him on DM).
I really think this one should be given another try to be a proper tune but sadly, Andrew said it's a long shot. Well, at least, we have this one as a trace it has ever been played live (for once)!
So this is kinda late as it's been two weeks since Rory's wedding BUT I noticed this since ages ago that the girl on the cover artwork of the single "Closer" is Amber, Rory's (now) wife!
