Question

In the song Can I Have This Dance (HSM) could not be May I Have This Dance?

I have a little problem with these words :c

Answer 1

Using "can" in place of "may" is a common error; so common in fact that for many people it sounds OK. In songs, especially country songs it is very accepted.

Answer 2

Yes, it should be "May I..." if he asks for permission.

Answer 3

Can is the informal way of asking for permission.
