i could 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

Start again begin again
Let's go down the waterfall
Have ourselves a good time
It's nothing at all
Nothing at all

What would I do?
What would I do?
If I did not have you?

Start again begin again
Let's go down the waterfall
Have ourselves a good time
It's nothing at all
Nothing at all
Nothing at all
