《重逢有日》是根据影片《日瓦戈医生》(Doktor Zsivágó)中女主人公拉丽莎的主题音乐填词而成的，因此也有人称它为“拉拉主题曲”(Lara""""s Theme)（“拉拉”系“拉丽莎”的爱称）。这段音乐自填词后，比影片本身获得更长的生命力，至今仍在世界各国传唱。
Maurice Jarre（1924— ）是法国作曲家，他1963年因影片《阿拉伯的劳伦斯》、1965年因影片《日瓦戈医生》、1984年因影片《印度之行》三度获得奥斯卡最佳音乐奖。
Some where, my love, there will be songs to sing,
although the snow covers the hope of spring.
Somewhere a hill blossoms in green and gold,
and there are dreams,all than your heart can hold.
Someday we""""ll meet again, my love,
someday whenever the spring breaks through.
……
You""""ll come to me out of the long-ago,
warm as the wind,soft as the kiss of snow.
Till then, my sweet, think of me now and then,
God speed, my love,till you are mine again.
