Good for you jj. That is a decent and free fix to cheer yourself up.
If I were to be on a sinking ship I would choose to be in your life boat and expect you to lead the cheerful singing :)
I have a certificate from the guildhall School of Music for singing when I was very young.
Now I might get one for impersonating
frogs croaking. And I can only sing in one range. I still have a good ear for music so never sing outside of my own four walls. I sound awful but at least I recognise I do.
