Another audio comic curiosity I stumbled upon. Back in the 70's there was a radio show in the vein of the old radio adventure series starring the Fantastic Four. I've only given a serious listen to the first one, and listened to bits and pieces of later episodes, but they seem to be straight adaptions of early FF issues. Stan Lee plays the announcer and Bill Murray plays the Human Torch (seriously, that's really him). There are 13 episodes on the Internet Archive (10 here
and 3 here
), one of which is a triple length episode featuring the Sub-Mariner. They're interesting little things, perhaps worth linking to on the issue pages.
