Color Theory - Once Upon A Time lyrics

Though I used to think marriage was a dreamer's religion My heart is dancing like a string of cans So if you accept and if you can spare me a lifetime We can hold forever in our hands Cause you can't rely on someone else In a million hours Will the love song fade into silence? Will the tears of rapture dry away? Though I have no doubt that you are my once in a lifeline In between the black and white is grey In some things you don't have a second chance Once upon a time Vows were spoken never broken People say that never happens Though I know you're mine Who can say that time won't change us People say we'll never be the same There have been some times When the effort shadowed the comfort And I felt like throwing it away But despite those burning eyes And despite the words that we tortured I never had a single lonely day You can't rely on someone else
