The Boys of Summer by Don Henley contains the following lyrics:
Out on the road today, I saw a DEADHEAD sticker on a Cadillac
A little voice inside my head said, "Don't look back. You can never look back"
I thought I knew what love was
What did I know?
Those days are gone forever
I should just let them go but-
The "deadhead sticker on the Cadillac" is obviously a piece of deliberate irony - owning a Cadillac is a symbol of upper-middle-class suburbia and "deadhead" is a symbol of youthful rebellion.
I'm particularly interested, though, in the line
A little voice inside my head said, "Don't look back. You can never look back"
Is Don Henley implicitly categorizing himself (or, at least, the narrator of the song) as a "Cadillac owner" (minus the Deadhead sticker)? Is the narrator a former "deadhead sticker" type who became a "Cadillac owner" type, warning himself that he's no longer a "deadhead" type?
