"Private Eye" 是由 The Beatles（披頭士）樂隊創作並演唱的一首歌曲。歌詞如下：
Private Eye
You better be careful baby
Don't you see what's going down
If you ain't with us
You better be careful baby
I don't know about you baby
But I'm telling you I can't be around
A private eye followed me downtown
Looking so ugly I hope he don't catch cold
It might set his nerves on edge
(Baby I can't tell him my troubles)
Cause if I try
I'm going to end up crying (oooh yeah)
If he doesn't have me locked up
Baby my baby and me we might get in big trouble
It might set his nerves on edge
(Baby I can't tell him my troubles)
Cause if I try
I'm going to end up crying
(Private eye)
You better be careful baby
Don't you see what's going down
If you ain't with us
You better be careful baby
I don't know about you baby
But I'm telling you I don't need him around me
Private eye can you help me
Get away from this love man and the people?
Cause I ain't no crook baby
But if you help me, then maybe I can come through for you (ooh yeah)
So you think you can take me for a ride
In your little black car baby?
You ain't got a clue baby
If I try, I might just cry oh yeah (private eye)
Private Eye 中英對照版歌詞：
你最好小心點，寶貝
你就不明白正在發生什麼事嗎？
如果你不跟我們一起，你最好小心點，寶貝
我不曉得你是否跟我同感，但我告訴你，我無法再跟你在一起了
一個私家密探尾隨我到市中心，看來如此醜陋，希望他別感冒了
這可能讓他的情緒失控（寶貝我無法告訴他我的煩惱）因為如果我試著去說，我會最後哭出來（私人密探）
你最好小心點，寶貝
你就不明白正在發生什麼事嗎？
如果你不跟我們一起，你最好小心點，寶貝
我不曉得你是否跟我同感，但我告訴你，我不需要他在我的身邊
私人密探，你能幫我嗎？
離開這個愛情男人和這些人？
我並不是個騙子，寶貝但如果你幫我，那麼或許我還能為你做些事情（喔耶私人密探）
