I'm going slightly mad! But I don't mind...

When the outside temperature rises
And the meaning is oh so clear
One thousand and one yellow daffodils
Begin to dance in front of you - oh dear
Are they trying to tell you something
You're missing that one final screw
You're simply not in the pink my dear
To be honest you haven't got a clue

I'm going slightly mad
I'm going slightly mad
It finally happened - happened
It finally happened - ooh oh
It finally happened - I'm slightly mad
(...)
It finally happened
I'm slightly mad
Just very slightly mad
And there you have it
