American singer, actor, bandleader, and entertainer (1901-1986)
- On my Fleischmann Hour from Rochester I went into a "rave" about the Victor record of ["It Must Be True"] as played by Gus Arnheim and his Cocoanut Grove Orchestra. From all reports that drift back to me, and from people that I know in California, Arnheim has the finest dance aggregation on the West Coast, and to my way of thinking, perhaps the finest in the entire world. It may sound like a rather broad statement, but I would be willing to back his organization against any other in any other part of the world. Although I have never seen them perform on the stage to what they have in the way of showmanship, from a pure musical standpoint I feel that they are unexcelled.
Perhaps my great admiration for them is increased by the presence of Bing Crosby, formerly the lead in Paul Whiteman's "Rhythm Boys", who, in my humble opinion, has the finest recording voice to which it has ever been my pleasure to listen. If he doesn't capture all the feminine hearts in America through his records, no one ever will. He has the most unique style of singing I have ever listened to since I used to enjoy the records of Charlie Kaley.

- At the microphone he is truly a romantic figure. Faultlessly attired in evening dress, he pours softly into the radio's delicate ear a stream of mellifluous melody. He appears to be coaxing, pleading and at the same time adoring the invisible one to whom his song is attuned. The bare microphone seems strangely cold and unresponsive to his serenading.
