I used to love singing! When we lived in Japan, we went to karaoke all the time. Mostly pop music, but singing is singing. And for the record, karaoke in Japan is not like US karaoke, which is not something I have a very favorable impression of. In Japan, each group gets a private room with its own karaoke equipment, you can order food and drink and you reserve the room for some amount of time. So you’re just singing with your friends, no one else. And Mr. SK has a beautiful voice. 
I also used to do more accompanying myself at the piano. I had a piano teacher who also taught voice and she taught me a lot of warm up activities and different techniques for bringing your voice out, and how to use your stomach to support your singing etc.
I got away from singing somehow and now my voice is out of practice and I can feel that I’ve sort of forgotten how to sing.
That’s ok, I have more than enough musical activities to keep me busy, but I can imagine that (if I ever get to retire…) I would enjoy joining a choir in the future.
