Unfortunately it used to be a huge problem for systems in North America that were
not on the grid, like film sets and music festivals running off generators.  Also
lots of people on boats.

These days the increasing use of inverter generators instead of synchronous 
types means that we can use Hammond organs at music festivals again and expect
them to stay on pitch.
