Bands that share royalties seem to have far more longevity and remain friends with less acrimonious breakups and expensive court cases. The Cure, U2, The Strangers are a few I can think of. I think it’s important to recognise the individuals input in terms of what they contribute musically as well as off stage. Morrisey for example maybe a gifted lyricist but I can imagine him being an insufferable tw@t in real life. In the early life of a band I can’t imagine him going out of the way to build an audience by being approachable to fans or venue staff and promoters. Before any success comes these things really matter. In the case of The Doors Jim Morrison must have been a nightmare to work with towards the end but the band always seemed to work with him and remain supportive.
