ceremony song

Can anyone recommend a song for me to walk down the isle to instead of the traditional 'here comes the bride' song?

*Keep in mind my ceremony is on the beach and i'm not religious.

Thanks girls!

I posed the same question yesterday and got lots of fabulous responses. I don't know how to post a link to another thread, otherwise I would. But, if you go down a page or two -- you should see a posting by me with the subject something like 'non-traditional song to walk down the aisle to'

Lots of people replied with great ideas!
