So why jam on the oldies at all? If the Tyros is as good?

Personally, I am delighted every time I get an opportunity to play one of the old standbys, and look forward to the opportunity to remind myself why they are STILL the goto sounds for most pop music. Every time I play one, I go back to my arrangers, and go 'Well, THAT'S not quite as good now I played the real thing!'
