Aha! Imogen Heap

[Intro]
La la la la, la la la la
La la la la, la la la la
La la la la, la la la la
La la la la la

[Verse 1]
Eat, sleep and breathe it, you're full of the stuff
Go back, get tied up tight
Wheat-, meat-, dairy-free, teetotal happy-clappy
High on life, you should try it, try it
And you know
Go on while no one's looking

[Chorus 1]
A-ha! Got you now!
Caught you red handed in the biscuit tin!
Cost you to keep me quiet

[Post-Chorus]
La la la la, la la la la
La la la la, la la la la
La la la la, la la la la
La la la la la

[Verse 2]
Golden boy boots, pocket pedal-stool
Picking sharp, smart moves
Plastic, tin can and paper separator
A busy bee wave, wave 'save the planet' flag
But sneaky in suburbia
