《老友记》大结局前的十年回顾（ten years of friends）中片尾的插曲叫什么名字？最好能告诉下载地址

U2

Walk On
And love is not the easy thing
The only baggage that you can bring
Love is not the easy thing
The only baggage you can bring
Is all that you can't leave behind...

And if the darkness is to keep us apart
And if the daylight feels like it's a long way off
And if your glass heart should crack
And for a second you turn back
Oh no, be strong

Oh, oh
Walk on, walk on
What you got, they can't steal it
No, they can't even feel it
Walk on, walk on
Stay safe tonight

You're packing a suitcase for a place none of us has been
A place that has to be believed, to be seen
You could have flown away
A singing bird in an open cage
Who will only fly, only fly, for freedom

Oh, oh
Walk on, walk on
What you got, they can't deny it
Can't sell it, or buy it
Walk on, walk on
You stay safe tonight
