"Hand on the tiller" is a British idiom that means:  A Steady hand on the tiller:  Full control over a situation. i.e./ "I felt comfortable knowing that even during this difficult time, he had a steady hand on the tiller."  So...putting it together: "Hand on the tiller" & "Eye on the wind" (first line of the song Everybody's Guilty") could be interpreted to mean "Stay strong in this difficult time. Everybody's guilty."
