Joe, NightWing, & LFF -- minor corrections to the above to my ear, bolded below. I agree with your line on cholesterol, Freddy:

Eat no meat,
Eat no meat,
Eat no meat at all.
Tofu treat and bulgur wheat,
Heed the vegan call.
If 'tween your lips some meat should pass
Any meal or snack
Cholesterol and fat you'll amass
And have a heart attack

No fast food joints we'll e'er enjoy
Barbecue no more
Serve legumes, grains, and beans of soy;
Or we'll boycott your store

Eat no meat,
Eat no meat,
Eat no meat at all.
Tofu treat and bulgur wheat,
Heed the Vegan call, ooooh...

[spoken by a bass]
Ask not for whom the dinner bell tolls.
It tolls for thee.
