I've never really thought a lot about the opening bridge music Phil Harris used on his radio show. But I was just listening to an internet station playing music from the 30s and they just played it. It's the first time I've heard the whole song. My music player says the song is called 'Rose Room.'
It wasn't Phil's version, it was by some band I didn't know.
