Marjo, who was named for Mary, the mother of GOD and Joseph, broke into the mainstrean sometime in the early '70s, I think. He was a young, tall, skinny, curly/mop-haired guy, who had been " preaching " ( in revival tents mostly ) since he was a toddler. He suddenly was EVERYWHERE on T.V. talk shows, documentaries were done about him, and I think that for a while, he was even in the movies. Then, he just as quickly disappeared. He was NOT a " televangalist ". He was more like some kind of " POP STAR ". It was weird.
Anyway, now, I hope you understand the refference. :-)
