any character duos that are mezzo-soprano and alto?

My friend (alto) and I (mezzo) are looking for musical duos that have our vocal ranges. So far (unsure how accurate) we have - Roxie and Velma (Chicago) - Juilet and Anne Hathaway/April (&Juilet) - Tanya and Rosie (Mamma mia) - Pearl and Dinah (Starlight express)

Help would be appreciated! (Songs and characters!!)
