I need help choosing a love song!

[eighthstarr]

Ok, I know this is cheesey, but I really need to learn a beautiful love song for my wedding. I know how to play basic guitar (as taught to me by my rocker fiancee), and I really want to impress him by playing a song for him at our wedding. It's really hard to find the right song because I am kind of an indie girl and I don't want to do anything too corny. I just don't know where to start to find a song that would be a good fit. I was thinking about learning "love" by john lennon. Something with a slight rock edge but really sweet and aimed at another person. A love song really sung to his/her lover.. Something by a female artist would be a good fit for me (since i'm a girl), and something that is doable on acoustic guitar. Don't know if you guys have any ideas out there, but I need help! Thanks a million!
