-Infinity
The OP asked what we sang. I stated what I sang by agreeing with someone that stated "I don't care." I have sang "I don't care" from 90' until this day. Same as my friends, my wife, and her friends. Never heard the other version, ever. I can swear with the best of them so it isn't becuase cursing offends me.
Not sure why you had to respond with a smarta$$ remark like -infinity. I didn't say one was better than the other just what I sang and still sing.
