Well, tough to hear them if they don't play them here!

But, overall, in the big picture of things, there's probably a piano solo on at least 100X's as many songs as there is a trumpet! (at a VERY conservative estimate).

Despite the move to synths, it is still the backbone of any keyboard player's needed sounds. Admittedly, if you let the arranger always play the piano part, and do simple melodies over the top of it, you may not really care that much about it. But if you do anything BUT that, a great piano sound is quite possibly your #1 needed sound...
