i wonder if any of you heard of old school song left left left right left getta on up getta on up if you know?

Answer 1

You would probably get more answers over in
Education -> High School, if it is a high school song, or
Education -> College & University if it is a college song.

Lots of people post general questions here; some because their fingers slip, some because they are attracted to the answerers, who tend to be wise, witty, gracious and devilishly handsome.

Answer 2

Sounds more like a military boot camp drill song--used to teach soldiers how to march together in a straight line.
