Maskman, aka Harmon Bethea, had a very long career starting in the late 40's with a group called the Progressive Four. Over the years he put out over 50 records under numerous names, the majority being issued as some variation of the Cap-Tans or Maskman & the Agents.
Here's a partial list of some of those names:

A good many Maskman records qualify as pure novelty, some are just plain weird...but there's some good stuff in there too.
