Arguably one of the best moments in the SNW Musical episode subspace rhapsody was Bruce Horak Cameo as the captain of the Klingon boy band. But there is a deleted scene of the opera version that while absolutly best scene won, would be fun to see released to fans
For those who need a Klingon opera fix sooner, DS9’s “Playing God” had the Klingon restaurant owner singing opera with Jadzia. Just watched this episode yesterday in my series rewatch. Not sure how to clip to a timestamp but it’s about halfway into the video below:
