The Avengers! On radio!?!
Those with fond memories of Honor Blackman and Patrick MacNee might be interested to know that The Avengers was a big hit on South African radio in the early 1970s. Yes, radio, and you can learn more about the show here.
There's also MP3s of several epsiodes that you may listen to here. And the shows are probably Kinky Boots free! (Boop! Boop!).
Thanks a bunch to April Winchell, odd music boffin, for the link.
