Confession: I started looking up songs for this show because I had an audition for it myself. I figured I might as well share the wealth. The show opened in 1991, but since the show takes place in the 1920's, it sounds older. The music is Cy Coleman, but the lyrics were done by Comden and Green.
Also if you've never seen Tommy Tune's Our Favorite Son, stop everything and watch this.
(You can cut to 3:47.)
Are you back? Good. Okay, moving on.
So even though this show came out in 1991, do not, I repeat, DO NOT sing a song from other musicals that came out that year, such as (notably) Miss Saigon. It's simply not appropriate. You're better off mining Comden and Green's older materials or "throwback" musicals from the 80s/90s, such as Me and My Girl, which is another show that sounds older than it is. The biggest parts, obviously, are Betty and Will, but the chorines and cowboys need to be able to sing as well. There are some serious soprano notes in the show. Don't believe me? Then you haven't watched the above. Go back and watch it now.
