You are talking to a man who can only play a plastic keyboard. Give me anything weighted and I've had it. I haven't got the strength in my fingers to push them down. So I don't get a lot of expression on the keyboard.
As far as friendships go things change even without the fame. People start moving on. I have a few friends that are married and are starting to have kids and I'm like 'Oh my goodness gracious - that's so insane.' I also have friends who are just doing their own thing which is cool.
