Lyrics:
I couldn't see, now I can.
I wouldn't listen, now I will.
He may seem happy, but he might be sad
You ought to be kind, you should do our best
can and could
will and would
may and might
ought to and should
You don't have to walk, no you needn't
Cause I'm able to drive, yes I can
We have to, We must obey the traffic lights
We can go on green but we mustn't on red.
Don't have to and needn't
able to and can
have to and must
mustn't and can't
