Could have been “be tough” instead since words taken from song but “get going” gets to have its day . We can toughen up another time. Why? well choice of “get going” always bemuses me in this song as rather than getting on with it as intended I always hear “get going” as run away. So much for those tough guys when you need them , more sense than to hang around in time of need. Cup definitely needs filling up , half empty but hopefully muzak will do the trick on an overcast , stormy summers day. So hear what you want and get going. Time waits for no man …or woman so they say.
Have a good day
