A lot of my friends are doctors, and the difference between me and them is there's no musical emergencies to pull me away from dinner. 'I need the chords for that song right now!' No, it can wait.
In times of joy and sorrow, love or hate, peace and unrest, music has always been an important outlet for expressing our emotions individually and as a nation.
When I was growing up, there was hate. I looked around and saw that it was so wrong. I got to go round the world with my rock band, and you can bring harmony.
