It is never too late to begin exploring new ideas... especially things music related.  Arrangers are evolving... some more, some less and who knows where tech will lead us.  Stephen, I'm so pleased to know "the light came on" at seventeen... and you did not waste your parent's investment in your future.  (Wish I had been fortunate enough to receive such a gift.)  I can only imagine how you are enjoying the Gig... and now beginning to mix in arranger styles. Good on ya', Mate! 
Dave,  It was the piano playing of musicians like Keith Emerson and Rick Wakeman that really got me motivated to start taking piano more seriously. I’m grateful they came along when they did.  Hearing Oscar Peterson also played a big part. 
This is a dream gig that’s for sure,  the only blood and guts here may be in another section of the building where the hospital operating room is 

.     Nice part about the gig there’s no equipment I have to haul, I just show up and play.
