Yesterday：昨天不再来 ----Beatles
美国MTV电视台以及《滚石杂志》共同评选的自1963年以来100首最佳流行歌曲中，这首《昨天》位居第一。――“昨天，我的烦恼似乎还如此遥远”，“昨天，爱还是件如此简单的事”，“可她为什么不得不离去”“我不知道，她也不肯说”.从1965年至1972年间有大约一千多位歌手演唱或翻唱过这首歌曲，这或许是世界上翻唱次数最多的歌曲。
《昨天》从曲式结构和节奏特点上采用了较为简单的两段式中的AABA形式，加上最后那个“姆”结尾句，实际上是最后A段结尾的重复演唱，曲式虽简单，但音乐的表现力却很丰富，具有很大的艺术容量。歌中讲述了昨日的爱情给我带来了无比的幸福，而失去了爱的今天是多么令人难以承受。快乐美妙的昨日历历在目，从而使人更加怀念以前。回避无爱的阴影，真好似《昔日恋情》中的某些情景再现眼前，也似《昨日再现》一样，都是昔日神圣幸福的爱的回忆。看来人们对失去的东西会加倍珍惜，爱情更是如此。
Yesterday 歌词 ----Beatles
Beatles(John Lennon and Paul McCartney)
Yesterday, all my troubles seemed so far away
Now it looks as though they're here to stay
Oh, I believe in yesterday
Suddenly, I'm not half the man I used to be
There's a shadow hanging over me
Oh, yesterday came suddenly
Why she had to go I don't know she wouldn't say
I said something wrong, now I long for yesterday
Yesterday, love was such an easy game to play
Now I need a place to hide away.
Oh, I believe in yesterday (Repeat)
Yesterday, love was such an easy game to play
Now I need a place to hide away. Oh, I believe in yesterday
