Zeppelin's Lyrics - I always thought there was some inside meaning to all this - is that time now?

And it's whispered that soon if we all call the tune 
Then the piper will lead us to reason. 
And a new day will dawn for those who stand long 
And the forests will echo with laughter.
If there's a bustle in your hedgerow, (TORNADO) don't be alarmed now, 
It's just a spring clean for the May queen. (MAY 1ST BELTANE - DURING THE ROYAL WEDDING WINDOW - is PIPPA the MAY QUEEN & the PIPER or is Kate the May Queen and Pippa the Piper?)

 

Two Timelines?

Yes, there are two paths you can go by, but in the long run 
There's still time to change the road you're on. 
And it makes me wonder.

 

That Whine in our Ears So many of Us Have?

Your head is humming and it won't go, in case you don't know, 
The piper's calling you to join him
