I have to say Diki you have really lost touch with what goes on in Europe these days.
Do a search for keyboard artists in Europe and you will find a boat load of gigging organ players, Male & Female, Young & Old, all transporting their own instruments?

Ummm a Hammond B3 weighs 310 LBs .... how many people have you seen carry one of these by themselves? I am guessing none. I don't think you are talking about the same sort of organs that we were referring to.
