Me and my friend have been asked to do a duet at the spring concert in 4 weeks time. We have been asked to sing a duet where the parts are equal.

I was wondering which duet should we sing, they are looking for a song that isn't that classical but well known eg. In a musical

Thank you in advance

What about singing a duet or two from one or more of the G & S operas? There are some lovely ones in HMS Pinafore if you have a good top to your voice. "O Joy O Rapture" is fun and well-known.
