Guild Films and C & C Television Corp distributed the RKO shorts of Edgar Kennedy, Leon Errol, The Newlyweds, and others for television broadcast.The Phoney Cronies print used on the Swing Parade disc was an Official Films home movie print. Sold for non-theatrical/non-television use. I have a 16mm print of this film, and the end title makes this disclaimer, so it's obvious that the Columbia "The End" logo was spliced onto the the ending of the print.
In the late 1940's, Columbia licensed a handful of their short-subjects material to Official Films, including "Phoney Cronies" and Brendel's "Yumpin' Yiminy" as well as Charley Chase ("The Wrong Miss Wright" & "Calling All Doctors", Andy Clyde "A Bundle Of Bliss", the first entry of The Glove Slingers series, Tom Kennedy and Johnny Arthur's "Half-Way To Hollywood", and Buster Keaton's "She's Oil Mine" and several of the Columbia "Community Sing" entries.
Now, was Guild Films and Official Films connected??? That I'm not sure of.
