Carmela, 

I think that the short answer is "no"

You are really looking at two groups of songs - those sung as duets with Gary - 

Play A Simple Melody
Moonlight Bay
When You And I Were Young, Maggie, Blues
What A Little Moonlight Can Do 
Down By The Riverside
Cornbelt Symphony
The Call Of The South 
Fatherly Advice


and the Christmas songs with various combinations of the boys.

Among these are
"The Snowman",
a medley "That Christmas Feeling"
"I'd Like To Hitch A Ride With Santa Claus"

To expand on this list search on each of the brothers in my listing here
http://www.jazzdiscography.com/Artists/Crosby/crosby1bDecca.html

For the CDs themselves, once you know what titles you really want, (given that they don't all appear on one CD), search on my listing at http://www.jazzdiscography.com/Artists/Crosby/crosbyIssuesCD.html

but I suspect that among the more recent issues you will need to look at the Sepia THROUGH THE YEARS series particularly volumes 2, 4, 5 and 6 covering the Gary duets and
for the Christmas songs 

THE CHRONOLOGICAL BING CROSBY VOLUME 51

BING CROSBY - THE VOICE OF CHRISTMAS from MCA

CHRISTMAS WITH BING from Pickwick (though this is now quite old) are potential candidates.

You could also of course try searching the likes of amazon both for names and titles.
If you find any CD that covers them all, please tell me, but I do not know of one..

I must point out also that the boys also appeared on the radio shows and some songs they participated in have appeared on various CD issues drawn from those shows.
