Oh, good spot! I was wondering when it would appear ever since Jarvis mentioned at the first Jarv Is show in Brighton that it was featuring in a film this year.
Kind of sounds like something most aligned with his debut solo album. Love Serafina's pizzicato'd harp parts.
Not sure if it would fit/be strong enough for an album if that ever materialises but it's half-decent.
Maybe that's what Jarv Is were recording in the summer...
