'I don't know which way the wind will blow.'

Continuing the U2 kick. Kite @ a performance in Boston. This is an earlier version of the song, before they changed the lyric from 'rock stars' to 'opera stars' for Bono's father.

Who's to say where the wind will take you?
Who's to say what it is will break you?
I don't know which way the wind will blow.
