Scarborough Fair is such a well known and often covered song but I always struggle with where cover performances belong - especially instrumentals. The reality is most American Artist releases with performances of Scarborough Fair will likely credit Simon & Garfunkel out of an abundance of caution and probably will use the long title even if it's an instrumental, so going by vinyl labels probably isn't ideal here. SHS set up the Simon & Garfunkel adaptation as a lyricization but we also credited Simon & Garfunkel for new music as well so now we have approx. 100 cover performances of Scarborough Fair down below the adaptation (when we typically would NOT do that). Sebastian said there may be a new melody element as well and to post this on the forum for feedback. If there is the new musical piece then we need to explain this in the Work comments and probably somehow give people guidance between the melody differences that are so great they require our putting instrumentals in the adaptation. You know me, I'm not a fan of musical adaptations because it makes it very difficult to assign covers and we end up with disparate treatment of like performances (and frankly, I don't have a good musical ear). My gut tells me we likely have a lot of instrumental covers parked in the adaptation that really could be in the Traditional Work (and the song titles really are probably not a good indicator of where they should go).
I'd appreciate any help here.
