I see the full Jarv Is lineup there in the after party pics. If that is Andrew McKinney, he has grown a whole lot of hair during lockdown. It looks gorgeous, quite jealous. Presume they played selections from Chansons D'Ennui?
The Brooklyn Vegan link confirmed that the full Jarv Is band play on the record, with added orchestration. Looks like it's credited as 'Jarvis Cocker' on the soundtrack album, and the 'Tip Top' pseudonym on 'Chansons' (just the sort of thing to cause an argument on Discogs).
