The performance is a beautifully polished and gleaming thing of wonder, but is just the small visible part that most of us see.
Below the surface and way down in the depths is something of almost unimaginable enormity.
Most musicians have gone through many years of dedication, devotion, study, hard slog, rejection, heartache, backache, fingerache, earache, and at times borderline poverty.
Nobody sees that part, and we actually don't want to reveal it to everyone when we're on stage.
This photo that I took today at Manchester Airport reminded me of all those many layers under the surface and shows a rather large layer that has been a major part of my life for the past 45 years.
I'm often asked if the travelling part of my life ever gets boring? The simple answer is... Yes, mindnumbingly so!
But that's not a bad thing... I learned very early on to embrace boredom and by doing that I brought to the surface my creative nature which manifested itself through a small cheap half size Russian guitar that my dad bought me at a market in London in 1960.
I had a very nice ordinary, dull, boring, working class childhood in a rather grey post WW2 Britain. Wartime food rationing had only just come to an end and many streets had large open areas where a house, or houses, once stood before they were destroyed in The Blitz taking the lives of entire families, including many of my own family.
I'm maybe painting a rather gloomy picture here, but that time was a wonderfully fertile breeding ground for creativity.
Just look at all the great music that came from Britain in the 60's. America seemed so glamorous and prosperous to us, and we all fell in love with America, especially the music, Jazz, Rock n' Roll, and aspired to all things American.
At that time in the UK we had the rather bizarre mix of curiosity, aspiration and boredom.
I'm grateful to boredom and am so glad I didn't grow up in a time where there was an endless supply of amazing things to do without leaving a computer screen.
It's great to learn new stuff, but it's just as important to give ourselves the time to absorb and process that stuff. Boredom is great for that!
I guess I'm rambling on here about nothing in particular. I'm just letting my mind investigate the undeniable link between boredom and creativity.
I wasn't going to post this, but I've still got 3 hours before my flight.... and I was getting really bored!
