I need Broadway songs about friendship?

Okay, so me and my friends (girls and guy friends) are doing a song at our chorus concert. The theme of the concert is world peace and friendship/brotherly love. We want to sing a song with one of those themes because if it isn't.. well then we can't sing it. We'd like it to be a Broadway song. There are about 10 of us so we can't sing a solo song unless there's a chorus arrangement of it. HELP PLEASE!
