Recent politics have suggested that everything we thought we knew was wrong. But against an economic meltdown and a major shift in global power, and in a time of complete uncertainty, one thing remains completely unchanged: the relevancy of the lyrics to Bob Dylan's the times they are a-changin'.

Come senators, congressmen

Please heed the call

Don't stand in the doorway

Don't block up the hall

For he that gets hurt

Will be he who has stalled

There's a battle outside

And it is ragin'.

It'll soon shake your windows

And rattle your walls

For the times they are a-changin'.
