I am not sure if this has been posted to the forum before (possibly so), but I recently found out that the Internet Archive has this impressive collection of Bing Crosby radio shows, most of them with really good sound. In case you weren't aware of this (I wasn't until recently), here's the link:
Thanks Anton for posting, I knew about that and it was there when I first heard Bing's shows. It is vert nice and I always thought that Bing Crosby could be understood better in radio than all other mediums.
I agree, Pantelis, and in fact, I would go so far as to say that hearing Bing talk on those CBS radio shows from the 1950s is almost as much of a treat as listening to him sing with the Buddy Cole combo.
