Robots In Disguise - Happiness V Sadness lyrics

I say, I say - today I'm on an up up upper Tomorrow I'm down Today I'm all right and I'm proper Tomorrow I'm why, why Yesterday I was switched on Today I'm turned off Yesterday I was someone Tomorrow I'm not Happiness versus sadness I'm like a yo-yo in a spin spin spin Happiness versus sadness I'm like a yo-yo on a string string string Have you heard the one about me I'm high and mighty And then I'm knocked out Whenever I'm Little Miss Smiley Later I'm crying loud Yesterday I was waving Today I'm all drowned One morning I cave in Another I'll bounce back Happiness versus sadness I'm like a yo-yo in a spin spin spin Happiness versus sadness I'm like a yo-yo on a string string string Doctor doctor she said to me - knock knock 'I can see why you're here, dear But I've got 20 minutes To cure all your woes and your ills Pop pills, head shrinks, quit drink I can prescribe for you' Can this 7.20 really beat my moods?
