Most influential 1960's song

Which is likely the most influential, reflective rock song on society from the early 1960's?

Is it from the from the Beatles?

No.

The most influential early '60's song that has the longest reflective affect since then runs verse like this:

One thing that I know is true. You'll be dead before your time is due. Yes you will.

See my daddy in bed a dying. See his hair a turning grey. He's been working and slaving his life away...

He's been working, yeah. Everyday, slaving his life away. WORK, WORK, WORK!

-The Animals.

THIS is the reward that awaits for those who follow the siren that work is good, being useful, fruitful, builds a good man. After all those years, the song still pertains to the strain of society todate.
