I have a friend who had a social (wives including Jerry Hall were included) dinner with Mick and other local (Dallas) business people. He sat next to Mick and Mick wanted to talk about nothing but business - Mick is a grad of London School of Economics with a Masters in Business to his credit. He is the brains and money guy for the Stones. Without him they would have been long extinct.
Mick is interesting. He may be obsessed with business but he also has the talent to be the singer and front man for his band.
I think you enhance his resume a bit:

Nonetheless, a smart guy and a Knight too!
I don't think Mick graduated the LSE. He effed up The Stones finances but was smart enough to convince Prince Rupert Lowenstein (financial advisor to European aristocracy) to come in and straighten them out and arrange for off shore tax havens. Prince Rupert Lowenstein managed Stones finances for about 40 years. All Mick Jagger had to do was to continue on the course that Prince Rupert put into place.
These days Mick pretty much manages the Rolling Stones Incorporated by having very capable people working under him.
Loewenstein was the Rolling Stones' business adviser and financial manager from 1968 until 2007.[2] In 1968, then working in London as a merchant banker, he was introduced to Mick Jagger by a mutual friend, art dealer Christopher Gibbs. According to Keith Richards, Loewenstein had never heard of Jagger before then.[12] Jagger was of the opinion that the Stones' then manager, Allen Klein, was not paying them everything they were due.[6] wikipedia
