There's a weblog for everything, including one devoted to the late Lawrence Welk and his musical family. Tell your grandma!
PBS in Seattle reruns "The Lawrence Welk Show" every so often, and watching it is such a wonderfully cheesy, innocent look back in time that I can't seem to stay away.
But then I also think of the Lennon Sisters, a quartet of sisters who were regulars on Welk's show once their classmate, Welk's son, introduced them to his dad. They left for their own show, and in 1969, their father was gunned down by a freakish stalker fan who delusionally believed he was married to one of them. So creepy, especially in context of the innocent world of the Welk show.
