Beatles Song to sing?

I'm doing this singing competition in class and the song for next class is a song by The Beatles. I've been having a hard time finding a song to sing since I'm not familiar with most of their songs and the ones I've looked at don't sound very good with my voice. I have a soprano voice and sing music like Carrie Underwood, Miranda Lambert, Faith Hill, Taylor Swift and Vanessa Carlton, so more country pop. I was wondering if anyone had any suggestions on what song to sing. I don't want to do one of there more popular songs like Here Comes the Sun, Hello Goodbye, etc. because that's what everyone else will probably be doing so fun of there lesser known songs would be better. Thank you!
