Well, I knew he was very delicate foodwise, so he could only eat certain types of food. I remember whwn the Beatlesd went to India, Ringo two with him two suitcases, one of clothes and another one full of food.
I don't Ringo was a vegetarian possibly until Paul preached to him the virtues in his mind about it. If he's into TM I do find that amazing since he wasn't into the Maharishi at the time.
all the beatles became vegetarians.and stayed that way....
