Does the singer Prince take pictures and sign autographs for fans?

i heard that he doesnt take pictures with fans or sign autographs but if i were to meet him and ask him for a picture or autograph will he really say no? i have met many famous people and never been rejected for a picture or autograph. does anyone know how he is with this because im going to one of his concerts in may and i wanna try getting to meet him by getting there early and staying late and hoping to see him come in or leave the venue and i would want a picture if i met him but i also dont want to be disrespectful if i know he doesnt do that stuff.

bonus question.... any ideas on how i can meet him?
