Watching Kipper with my son tonight, I was struck by the phrase "Ready, steady, go!" I don't often hear this sequence. In my upbringing, it has been mostly "On your mark, get set, go!"
I had thought the difference might be between British English and North American English, but when I search for "Ready Steady Go," I get a whole lot of unrelated hits related to music.
Is there a regional preference in the usage of these phrases to start a race, or are they perhaps associated with particular sports?
