Peter Pan with Jean Arthur and Boris Karloff (Columbia Records)
Although I believe there is no filmed performance of Boris Karloff playing Captain Hook, there is this recorded version, with the added bonus of the great Jean Arthur doing a Mary Martin as the original lost boy. As they do every week, the folks at kiddierecords.com have posted the audio from this double 78 r.p.m. disc set, along with all the graphics and even the label. You can just download the audio, or get a torrent .zip file with the whole shooting match.
Other recent postings include The 500 Hats of Bartholomew Cubbins (read by Paul Wing) and The Great Gildersleeve reading Hansel and Gretel and The Brave Little Tailor.
And, if you keep an eye on the site in the next couple of weeks, you'll get to hear Gloria Swanson doing Joey the Jeep. As she might say, viewing the state of recorded music today, "I AM big...it's the discs that got small."
