Hoagy Carmichael remembers Bix Beiderbecke

In this interview, Hoagy Carmichael rejects the notion that lots of people knew Bix well. He also mentions a song he had just recorded called "Old Man Harlem", which features a trumpet passage arranged like Bix would play.
Thanks to Nick Dellow for graciously sending along this recording which plays after Hoagy's quotes!
