Seems like a pleasant enough chap. Stuart Copeland really grated on him apparently according to a video on The Police I watched recently. The Police were not so famous until they came to America, they started out at local clubs, some quite small. I recall seeing one of their first acts at an iconic bar in Rensselaer NY called The Hullabaloo.
Copeland is probably the most influential drummer of all. You could even hear his influence on Neal Peart.
