A know a tab for this song is already out there. But some are terribly wrong and some of 
are silly mistakes.. there may well be some in this... but it's best I can do.

Look for the [G]bare necessi[G7]ties, the [C]simple bare ne[C7]cessities
For[G]get about your [E7]worry and your [A7]strife [D7]
I mean the [G]bare necessi[G7]ties or [C]Mother Nature's [C7]recipes
That [G]bring the [E7]bare ne[A7]cessi[D7]ties of [G]life


Wherever I [D7]wander, wherever I [G]roam, I couldn't be [D7]fonder of my big [G]home[G7]
The bees are [C]buzzin' in the [Cm]tree to make some [G]honey just for [A7]me
[A7]You look under the rocks and plants
And tak[D7]e a glance at the fancy ants, and maybe [G]try a [E7]few
The bare ne[A7]cessities of [D7]life will come to [G]you, [D7]they'll come to [G]you
