New video of the band in the studio. This marks the third one
At the beginning of the video Billie mentions Whatsername and that he's finally going to name the girl (the one he's written songs about from his younger years "fuck it, it's been 19 years") - so I'm pretty certain the song they start playing is 'Amanda' from one of their recent secret shows. Maybe. I'll wait for fans much more astute than myself to guess.
Thanks to Connor C. for sending this news.
