I grew up watching Mister Rogers' Neighborhood, which started broadcasting on PBS the year before I was born, in 1970. I have loved it, and him, unashamedly and without reserve, my entire life.
My friend Matti, is an age player, a gifted musician, and an absolute mushy emotional softie of the marshmallowiest kind (which is absolutely one of his best qualities.) Matti shares this same love for Mr. Rogers, and he sent me a link to a sort of song-mashup, based on old clips of the show. It's stellar.
Watch it. Like him, and me, you will no doubt tear up and smile when you do.
