I think jazzhooves misses the point though. Sure, when you are demo-ing a new arranger, you tend to play the Intros and Outros, play a few bars in the middle, on to the next style.... It might be easy to think that that is TOO easy. But real life, in the club or bar, you have to play the whole tune, make it interesting, make it entertaining.

THAT takes a lot more chops than just hitting 'Play'.

The way I look at it, I don't see a bold new generation coming along to take my gigs. There's a lot more to entertaining a crowd than holding a few arpeggiators down, unless you ARE playing to the techno crowd. Fewer and fewer youngsters have the patience to learn to actually PLAY, and consequently, once their initial 'play the karma functions' type of music changes (as music tastes always do) they will not have sufficient skill to adapt to new types of music. But I will...... LOL

It certainly makes me a lot more confident I will still be making a living well into my sixties...
