What happened here

[electric guitar intro] [verse 1] Being young we felt invincible Had no worries, did what we wanted The best of friends making our own way Now we fret about bills to pay [chorus] What happened here? Everything used to be clear What happened here? Pour me another beer [verse 2] Another day of punching the clock Gone from killing time to doing time Boss man with the paycheck shackles There’s the bell, another day done [chorus] What happened here? Everything used to be clear What happened here? Pour me another beer [Guitar and drum solo] [Verse 3] These chains weigh me down Getting stronger ever day I’m getting older, but also bolder I’ll be on top, you’ll see [chorus] What happened here? Everything used to be clear What happened here? Pour me another beer
