Recommendations please!

I will be visiting NYC in December. I have tickets to the Great Gatsby and the Queen of Versailles, but would like to try and get rush tickets or TKS for another musical while I’m there. I have Operation Mincemeat, Death Becomes Her, or Moulin Rouge on my list, but open for suggestions outside of those.

What would you recommend for a third show to see while in town? Also planning on seeing the Rockettes.
