In my uni days I did a karoake naked, but then I was high on the sauce. FWIW, it gave us a laugh at the time and now, 30+ years later, it is very much a cringeworthy memory. PS: One of the songs was (I'll be your) Long Haired Lover from Liverpool, the other being The Marrow Song (Oh! What a Beauty!) from the Rocky Horror Show (and this is one song I still like to belt out in the nude!! )
My ex wife and I did about a dozen years ago in Tx. It was a small ( and brand new ) resort. They had just hosted one of the nude 5k runs. We were the only ones ready to sing for about the first 90 min ( until more alcohol was on board ). It was fun
We have sung nude Karaoke at a few of the parties that resorts generally have on Friday and Saturday nights. She loved it, being on stage naked for the crowd
Not karaoke as such, but I have started or joined in singing in a sauna, where we were all nude or wrapped in a towel.
I've done nude karaoke with my friends. No, we weren't drinking at the time. We don't need alcohol to get nude. Yes, it was lots of fun and definitely not awkward. I've known these friends for years. We have all seen each other au natural while hiking, walking, swimming and most recently , a game of twister, that I posted about..
I would be far more confident standing in front of a group of people naked than I would standing in front of group of people clothed and singing. I can only assume that whenever I sing, a small innocent animal somewhere dies.
