an interesting question - when I was asked to make technics song disks for organised music lessons it was apparent to me that organs with pedals were seen as very uncool and naff by youngsters [even if they could reach the pedals! ]. As auto bass progressed and pop groups would not be seen dead with an organ as time went by it was no surprise to me that with no younger players the sector would die out leaving only a handful of affectionadoes. The popularity of keyboards is slowly fading if you look at total global trends over the years (compared to electric guitars for instance), and this must have a reason in the lack of music lessons/schools and examples in popular bands to stimulate interest in the young.
