I've mentioned the BBC Radio webcasts several times before. There is a really great one this time. BBC Radio 2 webcast will present a retrospective on the cornet in jazz. Included are tracks from Louis, Bix Beiderbecke, Joe Smith, Rex Stewart, Nat Adderley, Bobby Hackett. On-demand re-broadcasts can be heard this at http://www.bbc.co.uk/radio2/shows/bestjazz/. Look for "Best of Jazz" under the "Listen Again" link.
