Why is in raining in Glastonbury Daddy?

....... the naughty yellow pixies who pull the special, magic Climat-O-Levers which control the weather have been paid by evil capitalists with fat cigars in their mouth and $ signs on their pinstripe suits to make the world’s climate all horrid so that poor, underprivileged and disabled people and endangered creatures suffer – and that the reason we don’t know about it is because the media is run by evil Conservatives who want to keep this truth a secret.

So that's settled.
