22 was it, wildbill? ;-)
+1 your Bell Curve comment. Below, the first chart includes all genres and the distortion is caused by most jazzers' replying having 18" BDs. When filtered to just include rock, then we have a cleaner curve.
I actually enjoyed my job before retirement - I just disliked getting up to an alarm, commuting, meetings and politicised decision making!
Just to make sure everyone is happy with their representation:

BTW, where are the funksters? ... the Garibaldi and Chambers disciples? What about the fusioneers?
Jazz ... if someone says they play both rock and jazz I assume that to mean "mostly rock with some jazz or jazzy pop". In my experience serious jazz players (who play full jazz gigs and are accepted as "cats" in jazz circles) generally consider jazz a full time effort and, if they play any rock to make ends meet, they wouldn't mention it in this context.
If you are an exception to this assumption and I've wrongfully lumped you into the rock bag, by all means be a squeaky wheel!
