Linda Ronstadt sang the opening theme to Andy's short-lived 1970 series, 'Headmaster.'
Linda Ronstadt 'Only A Man'
Only a man
And he walks like a man along the path
Full of hills to climb without pause
Climb them because he's a man
Yes he's only a man
And he'll give you a hand up the path
Through the fields to climb if you will
Climb them until you're a man
