Sadly, Bela Lugosi and Alfred Hitchcock really don't meet; but here's some vinyl from Professor Kinema's archive where they lend their vocal talents to two old radio dramas. The first is Lugosi in The Doctor Prescribed Death, and the second has Hitchcock hosting Once Upon a Midnight. The recording of The Doctor Prescribed Death comes from Relic Radio, where you can find many OTR dramas, including horror. (I'll have the Hitchcock radio drama up shortly.)
