Some years ago there was a comedian named Charlie Manna who died quite young. I would like to find some of his routines if possible - whether they're on video or in writing. Where can I look?

On the World Wide Web. Type into a Google search (or your preferred search engine) the words, "Charlie Manna" and you should get a page that looks similar to this:
