"披头士"成员Paul McCartney是个动物维权斗士，长年以来，他坚持不懈地积极呼吁各界人士终结不道德和不必要的动物实验，将动物从实验室中解放出来。
今年10月23日，他为26年前的一首老歌《寻求改变》新推出卡通版MV，MV及歌曲收入将帮助善待动物组织"PETA"救助动物。
这首歌的歌词写道：“我们都在寻求改变 / 改变我们对待身边生灵的方式 / 这样我们才能学会成长”。
一起来听听这首爱心之歌吧，记住，善待动物=善待人类=善待自己。
Looking for Changes
I saw a cat with a machine in his brain
The man who fed him said he didn't feel any pain
I'd like to see that man take out that machine
And stick it in his own brain
You know what I mean
I saw a rabbit with its eyes full of tears
The lab that owned her had been doing it for years
Why don't we make them pay for every last eye
That couldn't cry its own tears?
Do you know what I mean?
When I tell you that we'll all be
Looking for changes
Changes in the way we treat our fellow creatures
And we will learn how to grow
When I tell you that we'll all be
Looking for changes
Changes in the way we treat our fellow creatures
And we will learn how to grow
When we're looking for changes
I saw a monkey that was learning to choke
A guy beside him gave him cigarettes to smoke
And every time that monkey started to cough
The bastard laughed his head off
Do you know what I mean?
When I tell you that we'll all be
Looking for changes
Changes in the way we treat our fellow creatures
And we will learn how to grow
When we're looking for changes
We're looking for changes
We're looking for changes in the way we are
