radiohead - i might be wrong lyrics

i might be wrong
i might be wrong
i could have sworn
i saw a light coming on

i used to think
i used to think
there is no future left at all
i used to think

open up, begin again
let's go down the waterfall
think about the good times
and never look back
never look back

what would i do?
what would i do?
if i did not have you?

open up, let me in
let's go down the waterfall
have ourselves a good time
it's nothing at all
nothing at all
nothing at all
