His hair was only to his collar and his beard was trimmed pretty close. Not like the 5 o'clock shadow look of today. That would have looked scruffy in those days.
He didn't go full-on hippy. Only his family thought so.
He did have an oh-so-cool grape colored polyester liesure suit though and I mde him a psychedelic purple print shirt to go with it.
Ever so stylish.
