Letra de Birthday Song

So it's your birthday and you’ve made it so far You have smoked and been to a bar You had sex, you got to drive cars You bought friends, you've reached for a star But who are you, Happy birthday to who? Now isn't too late To control of your fate Looking back will show (you) what defines you If your deeds were of made up needs Was it all then just a reaction? Were you biting the hand that it feeds... The real you Who are you? Happy birthday to who What's the matter with you
