My funeral wishes are to leave my body for medical research or direct cremation, no fuss, no bother and prepaid.
My father explicitly said he didn’t want anything remotely religious. My 2 sisters completely overrode his wishes and quite honestly it was really distressing. We had no idea re music- he never, ever showed any interest in any form of music (other than to say he hated opera and the Messiah!), definitely didn’t want hymns or prayers. They had the full blown works for his funeral.
I didn’t, thankfully, attend, I sat with my mother in her nursing home and we watched it online.
For her funeral she’d luckily written very clear instructions.
For mine, nothing. I will ask for there to be a family get together and that’s it.
