Gossip Friday: Crooner’s Union

From June 1945:

Clark Gable and Cary Grant have been served notice to join the “Crooner’s Union” or suffer the consequences. The threat comes red hot from Bing Crosby, Frank Sinatra and Andy Russell. Cary is going to warble several Cole Porter numbers in “Night and Day.” Clarkie-boy whips off a few bars of “The Trolley Song” in “This Strange Adventure.” If they can possibly arrange it, the day these numbers are recorded, Bing, Frank and Andy are going to sneak on the set and give out with a few Bronx cheers.
