I have learned things about him too since he died. Prince was always a hard guy to figure out. He had a weirdness factor up to eleven, but a lot of it seems to be just stage performance. He was apparently too shy to speak to people normally. If you could get to know him, he was apparently quite normal and not at all like him on stage. He did do a lot of charity work anonymously. At the time he died he was having a hospital built in Africa.
A friend & coworker of mine flew Prince & Mayte to London and they were in business class, if I remember her story correctly. She referred to them as “hipster doofuses” and said that Prince would not speak directly to flight crew, but would instead whisper to the wife, who would then speak to them. Sounds pretty affected to me.
