Some days ago I received an email telling me that I had missed some "interesting early Bing Crosby/Rhythm Boys records of 1926"  from the online discography.

These were listed to me as "When The Red-Red Robin Comes Bob-Bob-Bobbin'" and "Trudy"

Interest rising I asked for evidence and greater detail, and received an expansion on the information but no real evidence - 
 
Paul Whiteman's Orchestra With The Rhythm Boys (Bing Crosby, Al Rinker & Harry Barris), When The Red-Red Robin Comes Bob-Bob-Bobbin' Along  by Harry Woods (1926)
September 2 1926    36091    VICTOR 20177-B

Paul Whiteman's Orchestra With The Rhythm Boys (Bing Crosby, Al Rinker & Harry Barris), Trudy  by Charles Tobias & Al Sherman     (1926)
September 3 1926    36094    VICTOR 20177-A

Early? - I'll say so.  - Those dates are earlier than any other known records of Bing ("I've Got The Girl" was October 18th  1926).  And before the "Rhythm Boys" were formed,

So excitement rapidly beginning to cool, but the information sounded remarkably detailed.  More examination is clearly demanded.

I asked for evidence to back up the information, and if possible scans of record labels and audio copies. In response I was sent a link to an on-line Jazz anthology http://www.jazz-on-line.com/
and in particular to a "searched" page within it containing the terms "Bing Crosby" and "1926", which does indeed throw up these two songs precisely as listed.

This recital is already too long - to cut it short - I have listened to each record on line several times and the aural evidence confirmed my earlier scepticism. 

Neither contains the Rhythm Boys as we know them (Barris Rinker and Crosby).

Bing himself cannot be aurally identified. The singing group is obviously some combination of those who were used by Whiteman at the time, among whom Fulton, Gaylord and Young are possibilities. 

The record listing in the "Discography Of American Historical Recordings" merely shows it as being with "Paul Whiteman Orchestra" and "A Century Of American Popular Music" shows  it similarly.  Copies of the record label (found on line) merely say (as is usual) "with vocal refrain"

But not Crosby.  

Blood pressure eases off, heart rate drops, more relaxation indicated. 
I have sent a note to the person who runs the site.

It is too easy to jump to conclusions. Whiteman plus singing group does not equate to "The Rhythm Boys" and "The Rhytm Boys" outside the time frame 1927 - 1930 does not equate to Barris/Rinker/Crosby, though of course there was such a group after our trio had left Whiteman, who kept the name alive.
