Jack Armstrong on WRKO?

[Don]

I just heard a composite aircheck of Jackson Armstrong ("Your 
Leeeeeee-dah!")

There was one quick blip of a break of him on WRKO. (Sounds like 
overnights?)

I don't recall him being part of the WRKO lineup....must have been brief, 
no?

Does anyone know the story of Jackson Armstrongs short stint at WRKO?

(His wild style certainly sounded out of place on RKO...)

THanks!
