昨日 （Yesterday） / The Beatles ( 甲殼蟲樂隊)

“昨日”（英語：Yesterday）是一首披頭士樂隊的歌曲，原本為1965年的專輯《Help!》所作。雖然署名為列儂-麥卡特尼，該曲是由保羅·麥卡特尼獨自創作。

Yesterday, all my troubles seemed so far away
　　昨天，一切煩惱行將遠去
　　Now it looks as though they're here to stay
　　可我如今卻憂心忡忡
　　Oh, I believe in yesterday.
　　哦，我寧願相信昨天
　　Suddenly, I'm not half the man I used to be,
　　霎時，我與從前判若兩人
　　There's a shadow hanging over me.
　　她的身影總揮之不去
　　Oh, yesterday came suddenly.
　　哦，往昔在腦海浮現
　　Why she had to go I don't know she wouldn't say.
　　為何她不辭而別，姍然離去
