Yellow Music Orchestra - Sportsman + lyrics

I'm worrying everyday,
I could be anorexic
I'll have to get into shape
Can't seem to find the right charge
Your mother she might be a swimmer
Your father must of been a vaulter
Don't put me in skates
Ping-pong, I'm no great shakes
People say i'm weak
Can't even hold her tight
You're the star of the poolside
Your streamline curves i can't abide

I'll be a good sport
Be a good sport
I'll be a sports man
I'm not sleeping these days
Maybe insomniac
Quench my thirst, flesh and blood
I've got this craving for you
You brother they call him batman
Your sister we know she's a wonder woman

I'm seeing sundays
I could be apoplectic
The whole family gets in shape
Under the floodlights
People tell me i'm not strong
I can't seem to find the right charge
I'll be a good sport
Be a good sport
I'll be a sports man
