(they may not be exact, but here is what i got from
listening to the song part by part)

i'm livin here on the third speck from the sun
i think its about time i own world has begone
a place where my mind has all the color that it needs
a place where my tripy life just belongs to me

i want my own planet
the human race i cant stand it
i want my own planet
cuz this one here is a drag

ain't talking about no Hitler kind of trip
just want a place where things can be just as they wish
if you cant dig all these things i have to say
your gonna blow up this whole planet anyway

and that's why

i want my own planet
the human race i cant stand it
i want my own planet
cuz this one here is a drag

(solo)

i want my own planet
the human race i cant stand it
i want my own planet
cuz this one here is a drag

want my own

i want my own planet
the human race i cant stand it
i want my own planet
cuz this one here is a drag
