(Music) Business and ethic are words that doesn't get well together.
Artists are not accountant and often turn(ed) to be ripped by the ones in charge of their interest. What happened to Elvis was not isolated and countless ripping histories exists. Among them, the Rolling Stones have lived on both side. After a costly bad experience in choosing Alein Klein to represent them that ended by loosing the control on their Decca (London is the US) catalog, they did learn well about it and from RS Records put a financial organization controlled by them and devoted to them. You can't be an isolated dolphin when swimming in the sea of sharks.
Dire Straits on that point seemed to got a lucky star on them.
it's explained in the Oldfield book that from the beginning, John Illsley has always been the band member who was checking accounts.
In early days, it was him (and also Mark) who was "searching" for contracts, and after signing with Polygram, he always had an eye on the financial side.
That's why the band was in confidence with the record company, beacuse they knew that one of them looked at accounts, and sort of "accountant" of the band.
And of course, the relationship between Ed and the band, especially Mark, was based on friendship....until 1999-2000
