Harold And Maude (1971)

"You only need to know
Well if you want to say yes, say yes
And if you want to say no, say no
'Cause there's a million ways to go
You know that there are
And if you want to be me, be me
And if you want to be you, be you
'Cause there's a million things to do
You know that there are."

If You Want to Sing Out, Sing Out
Cat Stevens
