When she walked up, he walked down, just like the seasons went round and round. She was in love, he wasn't sure. She wrote some letters he tried to ignore. They could have been so happy together. They could have been so lucky in love. Sing la di da. So happy together. They could have run the earth, the sky, the sun. She carried his ring since she left school. He knew she was precious, the prettiest jewel. She wanted a baby, but he wasn't sure. He couldn't make up his mind anymore. They could have been so happy together. They could have been so lucky in love. Sing la di da. So happy together. They could have run the earth, the stars, the sun. I couldn't ever hurt no one. If you feel shattered I'm sorry for what I've done. We could have been so happy together. We could have been so lucky in love. Sing la di da. So happy together. We could have run the earth, the sky, the sun. Yea, we could have been so happy together. We could have been so lucky in love. Sing la di da. So Happy Together. We could have run the universe. Could have run the universe. Could have run the universe for fun. So happy together. So happy together. So happy together.
