I haven’t programmed this issue specifically, but Billy Strings has sat in with Trey Anastasio a few times. For me if they do a cover of the guests song, I would say it’s a cover until that member is added to the lineup. I would check how the PhishNet API handles it (I think they have a is_original Boolean). Phish does “covers” of the 2001 theme, I’d wonder if that’s considered a cover even though it was just a small tone poem from 100+ years ago??
