Lyrics

 * Join us now and share the software;
 * You'll be free, hackers, you'll be free.
 * Join us now and share the software;
 * You'll be free, hackers, you'll be free.


 * Hoarders can get piles of money,
 * That is true, hackers, that is true.
 * But they cannot help their neighbors;
 * That's not good, hackers, that's not good.


 * When we have enough free software
 * At our call, hackers, at our call,
 * We'll kick out those dirty licenses
 * Ever more, hackers, ever more.


 * Join us now and share the software;
 * You'll be free, hackers, you'll be free.
 * Join us now and share the software;
 * You'll be free, hackers, you'll be free.
