在《大话西游》中，唐僧唱《only you》的那一段台词如下：

```

only you can make this world seem right

only you can make the darkness bright

only you and you alone can thrill me like you do

and fill my heart with love for only you

only you can make this change in me

for it's true, you are my destiny

when you hold my hand i understand the magic that you do

you're my dream come true, my one and only you

only you can make this change in me

for it's true, you are my destiny

when you hold my hand i understand the magic that you do

```

此外，唐僧在唱《only you》时，还伴有以下台词：

```

only you can take me 取西经

only you 能杀妖精鬼怪

only you 能保护我， 叫螃蟹和蚌精无法吃我

你本领最大， 就是 only you

别怪师父嘀咕， 戴上金箍儿别怕死别颤抖

背黑锅我来， 送死你去， 拼全力为众生， 牺牲也值得， 南无阿弥陀佛

```

这些台词出自《大话西游之月光宝盒》中的情节，唐僧在影片中多次唱起这首歌，尤其是在他试图说服至尊宝跟随他取经时。
